Or maybe in Vrondiss, Rage of Ancients
The Haunt of Hightower The Haunt of Hightower feeds on discard and mill alike
(Each deals damage equal to its power to the other.) At the beginning of each upkeep, if a player cast two or more spells last turn, transform this creature
In fact, Tetzimoc, Primal Death is the only card in Magic history that can put prey counters on permanents, so chances are that if you arent running it in your main deck, having it in the command zone is pretty much worse than having any other commander instead
However, the power level here is very obvious and this will certainly see lots of play
And we can play the nice person with the same card and effect, so there is nothing to lose
