Mossfram Goliath

Reassemble —Discard a card. (Whenever this
creature dies, you may discard a card. If you do,
return it to the battlefield phased out under your
control with 3 reassembly counters on it. As long as it
has a reassembly counter on it, it doesn't phase in. At
the beginning of your upkeep, remove a reassembly
counter from it. When the last is removed, it phases
back in.)
Whenever Mossfram Goliath phases in, creatures
your opponents control get -4/-4 until end of
turn.
