Demonic Spawner

At the beginning of each upkeep, put a Spawn counter on Demonic Spawner.
Then, if Demonic Spawner has 3 or more Spawn counters, search your library for 2 Demon creatures, reveal them, put them in your hand, then shuffle.
Whenever a Demon you control dies, put a Spawn counter on Demonic Spawner.
Sacrifice a creature: Destroy Demonic Spawner. Any player may activate this ability.
