Thanks for the suggestions, guys.

Yeah Magnivore, I guess I asked for that one. Gaea's Cradle would be nice, but a little too pricey, especially when I have ten other EDH decks that are also money pits.

I understand what you're saying, Penthoplayer, but there are times when you just need to stay alive for that extra turn or two in order to win the game, it actually happens quite often. Platinum Angel can give you that extra turn or two, and it can be tutored for when needed.

Can you honestly expect that Platinum Angel does not get removed for a turn or two? Being both an artifact and a creature makes it vulnerable to the vast majority of removal spells. Sure, sometimes nobody cares about you anyway and they let you have your angel for a while because there are bigger fish to fry. But if one or more opponents really have the intention of knocking you out, i don't think the chances of Platinum Angel saving the day are all that high. Even your own mono-green (!) deck has >10 ways to remove it, if we count all the tutor effects that can find Acidic Slime or Silklash Spider. However, i obviously don't know your playgroup, so maybe i am just biased by my own experiences.
That said, isn't Elderscale Wurm better than the angel anyway? It gives 3 devotion, doesn't die to artifact removal or your own Silklash Spider, can be found via Green Sun's Zenith, and having a little more power can mean a big deal in combination with cards like Greater Good or Pathbreaker Ibex. The protection it offers is certainly a little worse than Platinum Angel's, but in my eyes that's a decent trade off.
Vigor is another card that i was wondering about. It's good against red sweepers like Blasphemous Act or Chain Reaction, but those can't always threaten Omnath anyway. It also has some nice synergy with Ulvenwald Tracker, but other than that, it gives you a couple of counters when your opponents chump block and prevents deathtouch (still very risky if opponents have instant speed removal for Vigor). Personally, i would prefer something that prevents blocking altogether, like Bellowing Tanglewurm (which isn't great if you face a lot of green and/or artifact blockers obviously, so that's a metagame call), Champion of Lambholt or Crop Rotation/Sylvan Scrying (to find Rogue's Passage).

Thanks for the comments, Emzed.

While you're correct that Platinum Angel is vulnerable to removal, and maybe more so than most, it's not a card I play early in the game when everyone at the table has tons of removal. I treat Platinum Angel as I treat Beast Within or Song of the Dryads, as a spot removal, except, instead of removing a permanent, it removes a win condition. It's only effective late in the game, and usually when there is only me and one other player left. I have lots of tutors to allow me to go get it or, if I already have it in hand, just hang onto it until I need it. Late game one-on-one, I only have to worry about that one person hanging onto to his spot removal until the bitter end. If it happens, and it has, so be it, I tried.

The reason I run Platinum Angel instead of your suggested Elderscale Wurm can be summed up in two words...'commander damage'. The angel protects me from losing to commander damage while Elderscale Wurm or Platinum Emperion do not.

Vigor allows me to chump block with Elvish Piper with no ill effects. Who doesn't love that?

Well, in that case i have another idea for you: Spike Weaver. It has the benefits of granting devotion and being green, can stop most lethal threats with its ability, and while you might need a total of 7 mana to make use of it eventually, you don't have to pay that upfront (the pure threat of activation might discourage attacks in your direction anyway). Also, it actually prevents damage, so in contrast to Platinum Angel, it protects your planeswalkers, you don't die when the opponent finds removal later on, and you can sometimes get a single Fog out of it even if they have removal right away.

Thanks Emzed, I knew if I strung you along long enough, you'd come up with what I need. /;-)

Funny thing is, I had Spike Weaver in the deck until about a month ago when I added Nim Deathmantle and had to take something out. There's a good argument, and you made it, that I should have taken Platinum Angel out rather than Spike Weaver. I think it will be less of a target for counter spells and removal, while allowing me that extra turn if needed. Even if the proposed attacker removes it prior to a lethal attack, I can activate it in response to get me past that turn. Down side...it's only good against combat damage, whereas Platinum Angel works against anything.

I like it though...it's back in...thanks!

Glad i could be of help. You are obviously right that if people in your playgroup use mill, or kill you with Exsanguinate, Nekusar, the Mindrazer or Purphoros, God of the Forge, you can't rely on Spike Weaver. That guy is only good if combat damage is actually relevant in the majority of your games, which depends on your specific meta.

Another card that might be interesting for your deck is the new Benefactor's Draught. I haven't had a chance to play with the card myself so far, but it looks versatile and powerful to me. It can give you extra uses out of your creatures with tap abilities, allow for some surprise blocks, draw a couple of cards, or just cycle on turn 2 if you need to hit land drops. Still it's really difficult to judge how good such a card actually is on average. Do you think it deserves a test run?

Yeah, I don't know. It could allow me to untap, say Selvala, Heart of the Wilds or Karametra's Acolyte and retap to load more green mana, but it also untaps everyone else's creatures so that they can retap for whatever effects they've got going on. So for that effect alone, Thousand-Year Elixir would be a lot better, but then there's the card draw aspect...

I'm also not sure when the best time to play this would be, and it's making my head hurt thinking about it. Could be, as you said, I just need to see it in action. As a one-off, even with the replacement effect, I'm not sure it's worth a card slot in this deck, but I could be wrong.

Dungrove Elder :)

Thanks for the suggestion, total_euphoria.

While Dungrove Elder isn't a bad card and it's in my treefolk tribal deck, it wouldn't make the cut here. All the creature cards in this deck have to do additional work to push the overall goal forward. I guess the closest thing to Dungrove Elder in this deck is maybe Ulvenwald Hydra, and while it cost twice as much to bring out, it also has power and toughness equal to all lands I control and not just forests, while allowing me to tutor any land card, which could be Maze of Ith, Rogue's Passage, Arcane Lighthouse, or whatever I need at the time. So Dungrove Elder just giving itself hexproof and having power and toughness equal only to the number of forests isn't quite enough value to be worth the card slot.

I do see your point but Hexproof is a valuable asset in a format dominated by removal :) Although it has nothing against sweepers :(

A format dominated by removal? I never thought EDH of all formats would be described that way, but i guess everyone plays and experiences the format differently.

I've seen a lot of play groups that use immense amounts of it, literally every turn. But I think you're spot on, pick cards that benefit you in your group right?

Carpet of Flowers could be insane in the right situation.

True, it's less reliable, but sometimes more powerful than Sol Ring in my experience. Certainly a card that only works if you are certain to play against blue decks at least 80% of your games, but then it's a fantastic card and has solid synergy with Omnath.

Thanks for the suggestion, K34.

Carpet of Flowers is a little too situational, and the situation is this...

If I'm playing against enough islands for this to do me any good, the island's controller won't let me use any of my mana anyway.

Damn blue players!!

/;-)

Say hello to my little friend Avenger of Zendikar

Blue decks only have so many counterspells! Make them use them all with all if the mana you have.

If you're worried about your spells being countered, check out Autumn's Veil. They'll never expect it :)

Thanks for the suggestions, guys.

Avenger of Zendikar is a beast in landfall decks,Herbenix, I've seen it do it's work. It's not nearly as strong in this deck though.

Yeah NINJAxPENGUIN92, but while blue decks only have so many counterspells, they also have almost all the card draw in Magic, a deadly combination, not to mention "Buyback" cards and the potential for a commander with a counterspell activated ability. My previous comment was a bit of tongue-in-cheek snarkism. I actually have a blue permission/thievery EDH deck, so I know from whence I speak. Damn blue players!!

As for including Autumn's Veil to fight off counterspells, sebvieira, it, like Avoid Fate which I actually had in the deck for a minute, aren't quite strong enough to make the cut. I really like the idea of Avoid Fate though. A green counterspell...what!?!

It's a shame we can't run hybrid mana in mono colored decks. Green counterspell = Guttural Response

I do like the idea of maybe trying Avoid Fate in my own deck though.

Ah, RamaLama, but Avoid Fate doesn't really prevent a counterspell. Still, didn't know about the card though and it's cool :)

Glimpse of Nature should be good.

Thanks for the suggestion, Penthoplayer.

While Glimpse of Nature is good combo card, so good in fact that it's banned in Modern because of the crazy shenanigans with Nettle Sentinel, Heritage Druid and low CMC elves , it wouldn't shine in this deck, because I have none of that, just a bunch of high cost creatures that I may be able to cast once a turn.

A one-and-done card like this allowing me to draw one, maybe two cards off of it, wouldn't be worth the space it takes up. True that I could bring it back with Eternal Witness or Greenwarden of Murasa, but even then it just feels forced.

Sylvan Library or Collective Voyage both seem really strong.

Sylvan Library to smooth your draws it draw more than one card per turn. Collective Voyage would be good to accelerate tour plan. While it also gives everyone mana, your commander benefits way more from it than anyone else (unless you are playing against something like azusa)
