All-out Pummeling

Target creature you control has wither until end
of turn. It deals 1 damage to target creature or planeswalker an opponent controls, repeat this
process until X damage is dealt this way. X is
3 times the power of your creature. If there are
no more legal targets, the remaining damage is
dealt to target opponent.
