Calving Glacier

When Calving Glacier enters the battlefield,
search your library for a Kaiju, then place it face
down in exile and shuffle. Put 10 ice counters on Calving Glacier.
Whenever you cast a Kaiju or a Kaiju you control attacks, remove an ice counter from Calving
Glacier.
{4}: Remove an ice counter from Calving Glacier.
When Calving Glacier has no ice counters on it, sacrifice it, then play the exiled card.
