Joseph Chadwick, Mutant

Menace, trample
Untapped creatures you control have vigilance
and "{t}: Target Mutant you control connives."
(To have a creature connive, draw a card, then
discard a card. If you discarded a nonland card,
put a +1/+1 counter on that creature.)

Tapped creatures you control have "Sacrifice
this creature: Target player loses 2 life."
