Proimordial horror

Trumple.
If a creature dealt mortal damage at primordial
horror, put three DNA counters on a creature
of your opponent. At the beginning of your
opponent's upkeep, remove one counter from
that creature. When there are no counters on
that creature, your opponent sacrifice that
creature. You put into play a 3/3 creature token Neomorph with Haste, Trumple and Double
strike. Sacrifice Neomorph at the end of
combat.
