Brainiac

Whenever Brainiac deals combat damage to a
player, that player mills a card.
Boast - {2}{u}{u}: Create a 2/3 android token
with the same abilities as Brainiac. If Brainiac
leaves the battlefield, bury this token.
(Activate this ability only if creature attacked
this turn and only once each turn.)
"Cause and effect. Resistance begets violence."
