Direhearth Lair

Direhearth Lair enters the battlefield with five
ice counters on it.
Whenever a player casts a creature spell with converted mana cost three or less, remove an ice counter from Direhearth Lair.
At the beginning of your upkeep, if Direhearth
Lair had no ice counters on it, sacrifice
Direhearth Lair. Then, put a creature card from
your hand onto the battlefield.
