Great points liquidjaguar...but I love these ideas being posted! So many near interactions.

I will certainly try a kiln fiend out as well. I've got several ideas now to test and I will go through a big testing session to see what works best! I'll update the list accordingly and re-feature this evening. Thank you much TO community for your support and great ideas! It's going to be an even better deck thanks to you all.

The two decks are really close together one is an Esper Delver brew http://tappedout.net/mtg-decks/15-01-15-KsM-esper-delver/ and the other is more of a mid range Esper deck that wants to equip Geist or Seeker http://tappedout.net/mtg-decks/08-01-15-esper-blade/ I keep bouncing it back and forth between the two ideas.

@liquidjaguar whenever you play an instant or sorcery Kiln Fiend becomes a 4/x, and makes Temur Battle Rage better

@,liquidjaguar also you have protection from red if you have Emerge Unscathed (or any other color) and you get +3 for every instant or sorcery you cast, so kiln fiend gets +6 and doublestrike and protection in one attack for 3 mana, or 2 if you're using Emerge Unscathed for it's rebound cost

Always preferred U/W/R over U/R, and this is the perfect explanation of why. Sick deck +1

We had a good time with cruise. Will the ban make this deck better or worse I wonder.

My thinking is it would be about the same. My impression is this deck is very offensive and wants to have a very fast clock and would not want to get into a long drawn out game. I'd probably go -3 cruise for +1 Path to Exile, +1 Serum Visions, and +1 Gitaxian Probe. Cruise was too good to not play it but I don't think the deck is broken with out it.

Treasure Cruise got banned :(

Obviously switching out cruise :(. runningwithbeers was right on it...jusf adding another of each Probe, Serum Visions, and Path keeps the deck pretty much close to as powerful as it was. Cruise was a great card; but it wasn't nearly as necessary here as it was in other Delver builds. I'm testing the new meta tonight (or at least what I think it will become) and will see if the band had any effect on this deck.

Fortunately the deck is pretty Strong against Junk and can kill/disrupt combo before they can get all their pieces. I've still got to get the best sideboard possible built as well; but that too will change with the shift in the meta.

Either way, i think this deck is actually still positioned well (fortunately) :)

Also...testing Kiln Fiend extensively tonight. I'll let you know how it goes!

Soulfire Grand Master might be a solid addition as well... I mean, it keeps your life up, which makes you less likely to get beat. Could be a good edge to hold off against aggro, etc., or possibly just a good card for the sideboard you're working on.

That is a really good point TheLoneDart...it is definitely a big contender for the sideboard (especially if the meta gets a little "grindier". You never know...the "buy back" could even come in handy every once and a while :) I will most certainly be testing this; and I could see it taking up a slot in the side board at the least.. Great idea!

rip treasure cruise. wizard pretty much said they want modern to be twin, affinity, junk and zoo. soulfire seems like a fine fit in that meta.

I know!! TC will be missed (although I didn't need it, I can tell you I certainly loved having the ability to relatively easily refill my hand for a cheap mana-investment :)

I do agree with you freyhackbarth as well as TheLoneDart that it potentially puts Soulfire Grandmaster in a great position. I am testing it now (and will continue throughout the week) and will update accordingly. I think at minimum it's making the board (if not one space in the main).

Great suggestions guys/gals. Thank you so much for your help!

This is the Monastery Mentor build me and CurdBrosBrewingCo were discussing if any1 is interested. UW Geist (With Monastery Mentor!)

Love it Crazybop09! I think a U/W control-ish shell is the perfect shell for Monastery Mentor. A lot of people were trying a more "tempo" shell (like used for Young Pyromancer; but I think you are on the right track with UW Geist (With Monastery Mentor!) to best take advantage of MM. Looks like what "control" could be in Modern (i.e. staying at 4-CMC or less but still having the ability to play a control deck...). Great list!

Really interested in Monastery Mentor. Looks like it could have a huge impact on the format.

Alright guys...so I tested Kiln Fiend....and you were all right! It is UNREAL in this deck. It has replaced Mantis Rider in the build and has made the build even more explosive than it was before. Thanks for the great idea guys!

Convoke....first off, I love your name :) I too love Monastery Mentor. I'm just not sure this is the best shell for it. In this build, Geist of Saint Traft is just the preferred 3-drop. I feel like Mentor fits best in a more "controlling" or "midrange" build that can generate multiple tokens. I still do need to test it though (as I haven't, and without testing it I can't be sure it's not a great fit here). With spells like Emerge Unscathed if Mentor sticks around even for just 2 turns he piles up tokens pretty quickly. I'll definitely give it a try (as it is a great idea)...I'm just not sure if this is the best shell for it. Crazybop09 actually just built a U/W shell with Mentor in it that looks really strong. Hopefully if he reads this he can post a link.

UW Geist (With Monastery Mentor!) is the list if your interested Convoke and CurdBrosBrewingCo what does Deflecting Palm do for you, im curious, in what match up's do you bring it in and why?

Hey Crazybop09....I tend to bring it in against Ad Nauseum (as Lightning Storm is the sole source of damage), Boggles (as they build up one huge creature and attack and often have lifelink somewhat early, anything trying to tutor in Emrakul, Tron (as it's great against Wurmcoil Engine, Burn (as traditionally it just acts as an additional copy of Lightning Helix against them, Affinty (as they often attack with one big creature with either Cranial Plating and/or a bunch of counters on it), Bloom Titan (as they like to attack with one very large Primeval Titan....

There are just so many uses. Even a smaller thing like a 5/6 Tarmogoyf can be crippling to an opponent as they were NOT expecting to get hit by the damage...often times they haven't calculated it in and either than very turn or the next turn is lethal. I've enjoyed playing it. quite a bit simply because I LOVE cards/effects that the opponent isn't ready for (i.e. most players are comfortable with countering/removing and attacking/blocking; but have a very difficult time with effects that are outside of these effects). It's worked well for me; but I can understand those not wishing to play it (as it is reactive in nature). I hope this helps!

CurdBrosBrewingCo had another thought this morning for a good replacement to cruise... I know this option would likely tap up more of your mana, however its a more flexible spell that's proven successful and purposeful in the pro tour already - Sphinx's Revelation. I see it as kinda of combining the merits of both cruise and grand master, while also keeping congruent with the fact that the deck you're running is not aggro; which Soulfire Grand Master definitely does give a more aggro edge. Anyway, just a thought!

CurdBrosBrewingCo One card you might want to look at as a replacement to cruise is Manamorphose I'm trying it in Grixis Delver Prowess and any time it's gold fished to three that card has been involved in getting the work done. I like that it cantrips for free mana wise giving you additional prowess triggers plus letting you draw into more gas. Also a small side benifit is at times it has helped mana fix to boot.

Sphinx's Revelation will really make this more of a control deck, which is not necessarily a bad thing. Of course the biggest downside of using it is it's mana cost, especially when all the creatures in your deck cost 1-3 mana. Somewhat takes away from the tempo aspect of this deck, but still a solid card to run imo.

TheLoneDart, Convoke, runningwithbeers...thanks so much for your help! I will certainly try out both of these ideas. Manamorphose is a great idea for Cruise replacement...at minimum it cycles, fixes your mana, and draws a card...essentially for free! Great idea. I will certainly try it. I am also building a deck with Become Immense in it...and Manamorphose is a perfect fit there too! Great idea....

Rev is a really interesting idea...it's one of those that can be better in play than it even seems in theory...and it seems pretty good in theory :) Thanks for your guys continued help!
