Swamp Tribe Temple

Druing your upkeep and end step create 5 5/5 Temple Guard creature tokens with Menace and Firststrike onto the battlefield and whenever a creature you control dies create a swamp temple counter.
{x}{4}{t}: for every swamp temple token sacrificed make a copy of target creature in your graveyard, only once per creature.
