Huitzilopochtli, War Jester

Indestructible, first strike
As long as the total power among creatures you control is less than 20, Huitzilopochtli can't
attack or block.
You choose which creatures attack each combat,
and who those creatures attack. You must choose
at least 3 creatures each turn. (If a player has less
than 3 creatures, you must choose all of them.)
