Aether Sink (Yellow)

Aether Sink enters the arena with a steam counter on it. **Action --** {r}: If there are no steam counters on Aether Sink, put a steam counter on it. **Go again** **Instant** -- Remove a steam counter from Aether Sink: Aether Sink gains Arcane Barrier 2 until end of turn. _(If your hero would be dealt arcane damage, you may pay {r}{r} instead. If you do, prevent 2 arcane damage that source would deal.)_
