I picked a solid selection from both blocks for this build.
I can't wait to enrich this deck with three more sets of Ravnica!
Crown of Convergence is very interesting. I am forced to choose between keeping something on top of my deck that I need but is not a creature, therefore cannot buff, such as a land; or a creature that is one or both colors (latter is a +2/+2 buff, which is great).
It's a tokens deck!
Conclave's Blessing can be used to make quite the fat butt on a creature.
Enchanting Privileged Position with Elemental Resonance generate five additional mana every turn.
Here, I only get a +1/+1 buff from Sunspire Griffin.
Here is the great buff from Collective Blessing.
Armada Wurm generates a 5/5 Wurm, and this is exactly the token I need for Populate triggers.
I can keep making 5/5 tokens for 1WG from Trostani.
And on top of the Populate benefit, I can buff +2/+2 in this board state.
And then keep making more 5/5 tokens.
And even more 5/5 tokens.
