Flood Ascendancy

Whenever a creature you control dies, put a spore counter on Flood Ascendancy.
At the beginning of your upkeep, if Flood
Ascendancy has 10 or more spore counters on it, remove those counters and return all creature
cards from your graveyard to the battlefield
under your control. Those creatures gain haste
until end of turn and are Flood in addition to
their other types.
