Rommel, Desert Fox

Menace, Blitzkrieg (Whenever this creature attacks, creatures you control get +2/+0 and gain trample until end of turn.)

If a creature you control deals combat damage to an opponent this turn, exile the top card of each opponent's library. Until the end of your next turn, you may play those exiled cards. If you cast a spell this way, you may spend mana as though it were mana of any color to cast it.

Whenever you cast a spell from exile, create a fuel token.
