Since I'm not doing Squirrel tribal (a strategy the commander kinda leans toward, but not really) because I think that's boring, everyone has done that already and this commander lends itself to other strategies, I'm going to look at what this card reminds me of and build that way
You'll also probably want to run some birds with flying, so it is easier for you to attack and activate Choco, Seeker of Paradie's ability
Xander feels like the type of commander where the person with the loudest voice or worst hot takes will target you simply for showing up and make sure to let you know they hate you because YOU chose to play that deck even though theyve likely never played against it before
This new iteration of Mizzix lets you copy any spell you cast from a zone other than your hand, which, I probably dont need to tell you, is really powerful
Other creatures you control will revert to their usual creature types unless another relevant effect is affecting them
