Deadpool, Trading Card Im still surprised Deadpool, Trading Card isnt acorn-stamped, because textbox swapping leads to some heinous rules interactions, and Im sure this card is being misplayed at so many Commander tables
Green decks often have massive creatures, especially since a deck with this commander likely focuses on dumping +1/+1 counters on their creatures
Oh, and a corollary: the Reserved List is never going away and whining about that makes no difference at all
Branching Evolution, Hardened Scales, and Kami of Whispered Hopes can increase how many +1/+1 counters you place on Marwyn, the Nurturer, which allows you to ramp into big win conditions like every green players favorite Craterhoof Behemoth
Its hard to effectively pressure Tevesh with this in play unless your opponents creature has flying or trample since the deathtouching snake trades for a creature, then another Snake is made before the next player can attack
If protecting your own is more your bag, then Slip Out the Back and Dive Down work well alongside Mist
