Crown of Convergence - 2 Artifact - Rare Play with the top card of your library revealed. As long as the top card of your library is a creature card, creatures you control that share a color with that card get +1/+1. GW: Put the top card of your library on the bottom of your library. First time I saw this card I thought it was a weak Crusade for any color. Then I took a good look at the secondary ability - an ability that should not belong to GW. The bad part about it is that it requires both G and W mana, meaning its abuse will be limited to said colored decks. But in said colored decks (ones that might also have a Mirari's Wake in there) it will allow to plow through the deck until you hit your combo-piece. I'd like to see if anyone can figure out a good way to really tie the two abilities together, specifically trying to use part 1 well. The +1/+1 is great with tokens, but tokens are often generated off of non-creatures, meaning that it could inherently have a low chance of activating the +1/+1. The second ability I think is what is going to carry this card, as its strong on its own, and makes plenty of other staples that much better (Sylvan Library, Scroll Rack, Divining Top).
