This is exactly the scenario I think where this card is appropriate. It's clearly a pretty big downgrade from Mulldrifter (evoke matters so much on that card), and tacking on 2 life at the cost of making it multi-colored is also a bad tradeoff. That said, if you want to tone down ETB value dudes this card is actually sort of sweet because it still does a lot of that while being harder to run and abuse. Instead of having a generic Ux value good stuff filler card (that goes in everything), you can make it a guild theme and tie it more narrowly to UW blink/skies or whatever. Neat.
This is pretty much exactly what I think of this card! Right now I'm actually having a little bit of a dilemma deciding whether I should swap in this card over
Basically Enabler v. Payoff card. I think I'm still on Team Brago, but its a tough choice. This is a gorgeous design for shaping a deck that wants to maximize value on it. And its better in some other UW deck that isn't going to be able to capitalize on Brago (like hard control, for instance)
Lots of hard choices from this set for me so far.
