By my count you're currently running 64 cards, so I would suggest cutting out some of the "1 of's" in the deck like Serene Remembrance Lay of the Land Martial Law and Death's Presence to start off with, and then maybe take out the Burst of Strength for 2 more copies of Selesnya Charm Also, Advent of the Wurm is a must have for all Selesnya token decks :)

Hm, Ill have to playtest the changes you suggested, that sounds like a bit of fun :) I also thought about removing some of those to make room for Voice of Resurgence

This is definitely a cool and flavorful deck, +1.

I would recommend removing Growing Ranks and Courser's Accord, which to be frank are not good cards. Growing Ranks is too slow since it does nothing for the first turn and the populated token can't attack right away, and Courser's Accord is just overcosted. Some possible replacements would be Alive / Well to stick with the Centaur theme and help trigger Angelic Accord, and Scion of Vitu-Ghazi for a powerful and impactful Populate that can also shore up your flying defense, since you currently look vulnerable on that front.

You also might consider taking out a couple Sundering Growth since its non-Populate effect won't always be relevant, and replace them with Druid's Deliverance .

-3 Coursers' Accord +3 Armada Wurm

having the 5/5 with trample is nice to populate.

Oh ya forgot about Armada Wurm . The one thing I would say in favor of Scion of Vitu-Ghazi is that he's more in line with your curve, since a six-drop is kind of out there on its own. And I really do think you need some flying defense. But both options are definite upgrades over Coursers' Accord.

Centaur Battlemaster ???

Armada Wurm would be a beast to play, but you are right, Scion of Vitu-Ghazi would give me that aerial boost im missing, and with Collective Blessing in play they will be good and set. Originally my air support was to be all angels but I dont always have Trostani in play or my other life gaining cards.

Centaur Battlemaster was orignally the main guy for this deck, because I absolutely love his ability. But unfortunately after setting the deck up to do heavy populate all he really did was get in the way. I had the same battle when I was considering to keep Ivy Lane Denizen or not.

what about Doubling Season and Parallel Lives for more late game evilness?

Oh yeah for the Sundering Growth thing. Normally I would agree with you but with the "Enchantment Creature" thing that Theros throws around so often its actually been much more useful than I thought. It gets rid of those pesky Bestow creatures, or the most annoying card in my opinion, Door of Destinies or Assemble the Legion .

rkreutz You are deviant and I love it. Those would be fantastic to play casually, but I would have to remove them when I go to standard tournaments.

Naturally. I didn't see if you have a format set. Also look into Door of Destinies . Heck, check out That is one big elf. It has a lot of clan synergy cards in it that might give you some ideas to make yours a little meaner.

Would door of destinies work for populated centaur tokens? Or only for the creatures I can play? It would be brutal if it worked for the tokens, but if not then I would have to go with the next popular which is Dryad. Brutal deck man, that would be a pain to play against.

+1 up vote!!!

you might want to slip a Fortify in there :)

Hm Fortify would be handy in a pinch, i'll have to consider that. Thanks for the vote :)

One of the key problems at the moment is that your populate mechanics cost 3 or more. When you're populating 3/3 centaurs for 3 mana then you're basically not getting any value at all - it's completely mediocre. If you're getting a 3/3 for 4 mana then it's even worse.

You don't have very many permanent sources of populate. Both the guildmage and Trostani are only 2-ofs. Growing Ranks is very slow and inefficient/ A further problem is that Sundering Growth HAS to target an enchantment or an artifact or it doesn't work - it won't let you populate. You can't destroy gods with it because they're indestructible so it really has very little use. Most of the time you're probably going to end up destroying one of your own things.

Actually I have had the opposite luck. Enchantment creatures are used here like its going out of style, so Sundering Growth has been a removal card that populates. Growing Ranks has been tying beautifully into Collective Blessing , especially since no matter how I shuffle I usually hit Call of the Conclave and Advent of the Wurm incredibly early in the game. so with a steady populate each upkeep, life flow from Trostani plus another wurm or centaur, all boosted +3/+3 unless I get both blessings out at once PLUS a spear, I dont see the inefficiency. And to top it all off, why not make that army of 6/6 minimal deadly to the touch? If anything, the synergy is strong, though not perfect.Within just a few turns I can have up to 4 centaurs, maybe a wurm.

Devout Invocation because why not. +1 btw

Maybe Fated Intervention ?

Also, when Nyx drops, you're gonna want Pheres-band Warchief.
