How exactly would you showcase these characters becoming Planeswalkers
Just having a 3/3 in play hits the 10-toughness threshold, and in a dedicated high-toughness deck, you can get many more benefits
This is a Dimir (blue/black) mill control deck that turns high-toughness creatures into win conditions and your opponents' libraries into empty promises
Additionally, there is no Shattered Glass treatment of Arcee, Sharpshooter // Arcee, Acrobatic Coupe
This sounds like a fantastic game plan in Commander decks like The Capitoline Triad and Karn, Legacy Reforged, which tend to play haymakers like Metalwork Colossus, Krang, Utrom Warlord, Meteor Golem, and more
For me, the more interesting part about this Secret Lair is Deadpool himself
