A small change, but I didnt like siding in Ghost Vacuum against Boros Energy alongside Wrath of the Skies to deal with Phlage
While it is a fragile 1/1 creature with a 2 CMC cost, it does provide an interesting late game play option
Cocoon would be a top-played removal spell if it could target an opposing creature
A little pricey, at 4 mana if it's not making you win the game, but it's potentially devastating, and can also be part of a "coming and going" strategy where you have multiple triggers when creatures or tokens come into play and are destroyed or sacrificed, which I like to do
With that in mind, FRF is the toughest set Ive ever reviewed
Or youre just trying to work your way towards something pricey, and, much like my middle-aged belly, youve got bulk to spare
