Assert Dominance

Ultimate - (You may only cast this card if you
control a creature named Ash, the War Machine.
If this card were to go to the graveyard, exile it
instead. When the associated creature dies, if
this card is in exile, shuffle that creature and this
card into your library.)
Whenever a creature you control attacks, it gets
+3/+0 and Indestructible until end of turn
I'll handle this.
