Frontul, Geyser Master

If one or more creatures would be returned to a
player's hand, return Frontul to its owner's hand
instead.
{1}{u}, Exile Frontul from your hand: Frontul
gains flash until end of turn. You may cast
Frontul from exile by paying {2}{u} or
{p/u}{p/u}{p/u}{p/u}. When you cast Frontul
this way, return up to two creatures to their
owner's hands.
