My votes:

G/B: Unending Death

I agree that there are a ton of sweepers in the format all ready, but the beauty of this is that it acts as a sort of pseudo-sweeper, and it can lead to some really fun board setups. I hate to vote for my own card (feels a little cheap to me) but out of the three it's the one i liked the most.

G/W: Morglen Necromancer

Again I hate to vote for myself, but I felt like it was a very solid card. The others either felt a little weak, or a little strong, or just felt like multiple cards rolled into one. I like the flavor, and the utility and unfortunately I chalk another vote for myself.

G/B/W: Morglen Witchdoctor

I really like this card and i believe it fits nicely in GWB. I believe that GWB would be a decent cost for it but seeing as how it would be more difficult to cast make it a 1/3 and change the creature type to treefolk druid. It makes sense flavor-wise and elves just don't feel at home in GWB... but that's just my opinion.

Touch of Morglen, Wherefore Death?, Wandering Hermits.

For Wandering Hermits, maybe make it an Elf Shaman?

WB: Unending Death is hilarious. It also happens to be an extremely cheap creature token sweeper. It's almost pointless when cast early (almost because of ETB, "dies", and LTB effects) and better when cast late. For being the most interesting WB card, it gets my vote.

GB: Gravecradle Moss, I think, has a good chance of becoming OP. Here's how to abuse it for its full worth:

When the non-token Gravecradle Moss dies, don't exile it. Let Memento trigger. When the token Gravecradle Moss dies, exile it and return the dead Gravecradle Moss card to your hand. Repeat until your opponent concedes.

I made Pathcutter Zombie to be an interesting take on Sakura-Tribe Elder , but in the end, I don't feel it's as OP as Gravecradle Moss. (Sure, Pathcutter Zombie also reads, "1GB: Search your library for two basic land cards, put them onto the battlefield tapped, then shuffle your library", but it does seem a bit boring.) Thus, Gravecradle Moss takes my vote.

I propose making Tharin'l Rituals an Enchantment.

GWB: Ugh. Tough choice. I'll vote for myself here and give it to Dasvol, Tharin'l Superior. I've read the winning and voted-for cards and thought they all promoted Memento...up to a little too much. Like when Wizards said in a Daily MTG article that they created Creeping Corrosion to be an artifact hoser in an artifacts-matter block, I created Dasvol to be a more flexible Memento hoser in a Memento-matters block. Ultimately, since cards like him are rare, I think he still belongs, but he should prevent Memento from completely taking over the block. Wizards said in the same article that they made the mistake of not putting in artifact hosers in the original Mirrodin block. I believe we should not make a mistake like that here.

Honorary mention to Pulse of Morglen, though. It's land destruction at worst and pretty flexible at best. And, it recurs! Too bad it can't hit planeswalkers unless they're named Gideon Jura .

I propose renaming Sacred Wolf "Revered Wolf" and making Wandering Hermits an Elf Shaman. I also propose changing the "Hexshroud" on "Revered Wolf" to Hexproof.

WB - Elf Lifemage. I like it alot, but I feel to get the most effect out of it, it should come out a bit earlier, perhaps by dropping it to 1(w)(b) and making it a 1/3.

GB - Yeah, I'm gonna be that guy and vote for my own cards. Gravecradle Moss is probably overpowered, and as Lectrys points out, not exiling the non-token keeps him coming back for more ramp. This is how I intended it, however I have a feeling it has the potential to be too powerful.

GWB - Pulse of Morglen. Yes, I agree its underpowered. I think to bring it up to where it needs to be, either it should be an instant or possibly leave it a sorcery and let it target any permanent.

And I just want to point out that Unending Death is my favorite card I've ever submitted for this contest.

I forgot to mention this earlier, but one important thing about Pulse of Morglen is that it's 3 cmc land destruction. Look at that!

Unending death. Truly great concept, though maybe the cost is not fair. Imagine I attack with a bunch of 4/4 and the opponent and lethal on the board, then I cast Unending death, all my creatures reappear untapped (imagine if those 4/4 were obstinate baloths!), simply unfair! I'd raise the cost.

Rapid Burial is the best card there, bust the effects are a bit too much. T1 mana dork, t2 sac i have 2 fresh lands AND draw a card? And if I have 4 creats in grave I have like 4 mana available with 2 mana spent AND a card? That's like Primeval Titan for 2 mana, not like Harrow that sacs creatures. Not to mention this will trigger some Memento. I'd say to remove one ability (drawing a card is the most busted: sac your 1 p/t guy, draw into big papa. the other is interesting to keep), and lands should come into play tapped.

Rapid Burial BGInstantSac a creature, then choose 2 basic land cards from your deck and put them on the battlefield tapped.(Draw a Card)If 4 or more creature cards are in your graveyard, add BG to your mana pool.

Memento is cumulative? I mean, if a creature has 2 instances of Memento, you get 2 tokens out of it? (Like, Memento 1, Memento 2, etc?) If so, it would be great to have

Dasvol, Tharin'l Superior BGWLegendary Creature - Elf ShamanAll other creatures you control have Memento.When a creature your opponent controls dies, exile it instead3/4

@gustha, are you voting for them?

Also, as I said earlier, I meant Dasvol to be a wider version of Memento hate. He doesn't play nice with creatures you control with Memento, and he's so haughty that he isn't supposed to.

I am open to change how would

Rapid Burial

BG

instant

Sac a creature; then choose 2 basic land put them into the battlefeild tapped if 4 or more creature cards are in your graveyard add BG to your mana pool and draw a card.

also could change number of creatures needed.

@lectrys:

I'm voting for them. Except Dasvol. if it's going to stay like that, anti-memento... mmm...I suggest:

Dasvol etc. BBGWLegendary etc.SwampwalkIf a token would enter the battlefield, it is exiled insteadBGW: Dasvol etc. loses all abilites until the end of turn3/4

Upgraded the cost and the thoughness it doesn't lose to random bolt/giant, added some evasion, and a nice feature that allows you to use memento if you want it to. Swampalk just for flavour, so it seems a rejected elf exiled in the marsh who got back to get rid of his ex-kin. Anti-memento is now like a corruption of his soul in exile (BB on its casting cost), and being and elf it is thus explained why he knows how to stop the magic that duplicates dying elves. (Like stripping the shadow off Peter Pan, isn't it?)

Tell me if you like the idea :D

@rapid burial. I always feel the "draw a card" is too busted for a (essentially) mana acceleration spell. I mean, sac a creature make mana is good and very in flavour for a BG card. Still... Mm... let's try out something more complicated:

Rapid BurialBGInstantAs an additional casting cost, sacrifice a green or a black creature.Search your library for up to two basic land cards, then put them onto the battlefield tapped.Then, if your 4 or more creatures are in your graveyard, choose one: add BG to your mana pool; or: target player draw 1 card and loses 1 life.

The spell is again just awesome and needs some other power restriction imho. Some changes to the wording: sacrificing a creature is now an additional cost, so once you've cast the spell, no one can respond removing the creature and making the spell fizzle. Maybe this could be errated, if no other option is viable. The other two effects are choosable: either you add mana, OR draw a card and lose life. (Note that you can use the card to make your opponent draw and lose life-this can be errated too.)

W/B - Elf Lifemage - I think it is fine as is.

W/G/B - Dasvol - I like the idea of having anti-memento in the set

G/B - Rapid Burial - like it as is.

@gustha, I'm not a fan of giving Dasvol the ability to lose all abilities, but I always did think Dasvol wasn't well-liked by the other elves, especially the Gladeparters. (He just feels so above the lowly tokens that he exiles them on sight.) Adjusting his other stats is okay, though, but don't make him a 5/5 or 1/1 or something.

Elf Lifemage

In order for this to be black/white I think it should drain life. Whenever a token is made by a creature with memento, you gain X life and target player loses X life. I would change P/T to 2/2 to compensate for the added power level.

Rapid Burial

This is going into every commander deck with GB. I'd like it even better as a 1GB instant so you can sacrifice in response to board sweepers/burn/etc. if mana is open. Living the dream: sac sad robot to this.

Morglen Protector

Flavour is awesome on this card and yet a totally non-parasitic use of memento. Suggested wording for first ability would be Kicker: sacrifice a creature: Morglen Protector has flash.

Note: Morglen Witchdoctor was a close second. I'd make it BGW, and have P/T 2/2.

I think to make the wording on Morglen Protector less clunky it could say something like: "You may sacrifice a creature as an additional cost to play Morglen Protector. If you do, you may play Morglen Protector whenever you could play an instant." Then you're neither using kicker nor flash. Or perhaps: "You may play Morglen Protector whenever you could play an instant if you sacrifice a creature as an additional cost to play it."

What about "Sacrifice a creature: Morglen Protector gains flash until end of turn. Activate this ability only if Morglen Pretector is in your hand."

I got the wording for the last one of off Greater Gargadon .

Another idea: give Morglen Protector flash and "When Morglen Protector enters the battlefield, if you cast it any time a sorcery couldn't have been cast, sacrifice a creature."

Or: "You may cast Morglen Protector as though it had flash. If you cast it any time a sorcery couldn't have been cast, sacrifice a creature." This I got from Armor of Thorns and its ilk.

Here are my attempts at templating, in part, some of the other cards.

Elf Lifemage: "Whenever a token with memento enters the battlefield, you gain life equal to its converted mana cost." Also, shouldn't it be called Elvish Lifemage?

Touch of Morglen: "Destroy target creature. You gain life equal to that creature's toughness."

Rapid Burial: "As an additional cost to cast Rapid Burial, sacrifice a creature.Search your library for up to two basic land cards and put them onto the battlefield. Then shuffle your library." and "If there are four or more creature cards in your library, add BG to your mana pool."

Gravecradle Moss: "When Gravecradle Moss dies, you may exile it. If you do, choose one -- draw a card; or return a card from your graveyard to your hand."

Tharin'l Rituals: I like the design team's idea.

Sacred Wolf: "Hexproof."

Morglen Witchdoctor: "When Morglen Witchdoctor enters the battlefield or at the beginning of your upkeep, put a 0/1 green Plant creature token onto the battlefield."

Unending Death, get's my first vote. I'm a control player so I love me some field wipes.

Pathcutter Zombie, get's my second vote. Nice ramp on a decent body for it's cost + memento.

Pulse of Morglen, get's my third vote. Nice destruction that's reusable.

I agree

Unending Death - Needs something though. Maybe under costed? I'd love it as a 3cmc instant spell

Pathcutter Zombie - Love it. Sakura-Tribe Elder x2 anybody?

Pulse of Morglen - Destroy non-land, but remove the tapped clause

B/W - Unending Death. I agree with Jarrod_0067 though; if it were a 3cmc instant, it would have more uses than just clearing tokens or essentially negating a creature's memento. It could also act as a safe passage. For example, your opponent is attacking you with a bunch of creatures. You could blow Unending Death to spare yourself for a turn.

B/G - Pathcutter Zombie. I absolutely love this card. It's one of those cards that's amazing in almost any situation, without being one of those broken game changers. Reminds me of a Primeval Titan in weenie form.

B/G/W - Dasvol, Tharin'l Superior. I personally feel that every set needs a card that goes against it's theme. Kind of like Melira, Sylvok Outcast against infect.

For white black i want the Morglen Witchdoctor. That would be a great and awesome card to add to the set, and i wasn't particularly fond of any of my other white and black choices.

Green and black: I went Pathcutter Zombie because i felt that the rapid burial was just too abusive in the set.

Tri color i vote Morglen Protector. Seems like a lot of the others were op especially hexproof w/ super land walk.... this is a multicolor set afterall... and hexproof w/ protect from creatures is also a nono in my opinion. My only concern is that 4 power...it might be too high may have to lower it to a 3/3 b/c of all the awesome stuff it already does.

On the Morglen Protector... for verbage. "As an additional cost to play Morglen Protector, you may sacrifice a creature. If you do, Morglen Protector gains Flash."

Ok winners and new challenge are up
