Nox gatekeeper of death

Deathtouch
Affinity for zombies (This spell costs {1} less to cast for each zombie you control)
At the begging of your upkeep return target zombie from your graveyard to your battlefield. This does damage to target player equal to that zombie's power.
{b}{t}: You may return this to your hand. It gains dead storm. (When you play this spell copy it for each zombie spell played before it this turn except those copies are not legendery.)
