Absorption Dome (CRU104) (Unlimited Edition) Rainbow Foil - Crucible of War

Absorbtion Dome enters the arena with steam counters on it equal to the number of times you have boosted this turn.
If you would be dealt damage, remove that many steam counters from Absorbtion Dome instead, then prevent damage equal to the number of steam counters removed this way.
When Absorbtion Dome has no steam counters on it, destroy it.
