Mavuika, God of War

Creatures you control have haste.

Whenever you attack you may reveal the top two cards of your library, exile one of them and put the rest in the bottom of you library.
Whenever a creature you control deals combat damage to a player you may cast an exiled card without paying its mana cost.
{5}{r}{t} : Create four copy tokens of target nonlegendary creature you control, sacrifice them at the next endstep.
