Main combo idea here is that, because Sigardian Evangel puts atleast 1 copy in our graveyard, being able to play it from our graveyard means we can always refill the board and tap-out our apponent.

Sweepers: Since we can repopulate the board easily, this creature deck can actually run lots of sweepers.  Also, since we are so willing to kill our creaturees and bring them back, you'll notice we focus on creatures with strong ETBs.  In that way, this deck has a very Blood Money Deck feel to it, but in Selesnya.  For sweepers, we are choosing Doomskar for speed, Begin Anew for buffs, and Ondu Inversion for land.

Recursion: Dollhouse of Horros will make it so we can spend all our mana on Evangel every turn.  We also have The Restoration of Eiganjo // Architect of Restoration that can pull anyone back to the board on earlier turns, plus ramp.

Ramp:  Late game, we want to be flooding the board with Evangel and Tapping the enemy out every turn, and we need a fair bit of mana to do this (around 7, but more is always better).  That's why the deck has a variety of Creature-ETB ramping and smoothing cards.  Kami of Bamboo Groves (can both ramp and smooth), Prosperous Innkeeper (one of few life gain sources), Professor of Symbology (can grab Enviromental Sciences), and honorable mention Ambitious Farmhand // Seasoned Cathar (also great in the deck, but cut for the card advantage and versatility of the Professor).

Responses:  Sweepers by themselves are usually not enough to deel with all major threats, so we also carry Creature-ETB spot removal with Skyclave Apparition and the Professor who can grab Reduce to Memory (giving them a 3/2 token often isn't that bad since we are so willing to sweep and trade) and Containment Breach.

Novalties:  Getting Evangel's cost down from 2 to 1 doubles the number we can play each turn, so Cemetery Prowler is a really fun addition, even though it's a bit win-more, and he provides a bit of graveyard hate which shouldn't be understated.  Antique Collector's ability to give us card draw for dead creatures is the Blood Money equivelant to Skullport Merchant.  She's obviously better to play when there are creatures on the board, but don't be afraid to play her on curve or as a chump blocker, as she'll go right back into our deck, so we'll see her again.  Remember that her affect is permanant, so she only needs to paint each creature once for them to perpetually jump back into the deck.  Also, her ability and Dollhouse are a bit of a nombo, so from time to time we might actually prefer to leave our creatures in the graveyard.

Land:  Since we need as much white mana as we can get for Evangel board flooding, every source of green mana is a detriment to us.  That's why The World Tree is actually a great card, that would otherwise seem too slow for this deck.  When you get to the Evangal flooding portion of the game, all your green sources turn into white sources.  We then have a minimal number of value lands, and basics in green, everything else can produce white.
