You also wouldnt play Llanowar Dead over Three Visits as Three Visits only requires green mana, it can fetch lands that tap for multiple colors, and its ramp effect isnt tied to a creature that will likely disappear after your games first board wipe
Adding in discard elements and cycling generally takes time, so it will take something special going on for this to be a real player
You choose which player, planeswalker, or battle Senu is attacking when you put it onto the battlefield attacking
A creature you control that's both a Zombie and a Mutant will get only two +1/+1 counters from Vault 12's last ability
The adversaries synergize with just about everything: theyre an amazing hit for Claim/Fame, they come back with Lurrus of the Dream Den, they make tokens to sac to Village Rites, and they of course pump up the Champions
