If Blastcone Fae is played from hidden and its triggered ability targets an opponent's unit with -2, can the opponent use Void Seeker as an action to kill Blastcone Fae before the -2 resolves?

Ruling: No, the opponent cannot play Void Seeker in response. The Blastcone Fae's triggered ability goes onto the chain and will resolve even if Blastcone Fae is killed, because the ability does not reference Blastcone Fae itself. Additionally, actions can only be played when the chain is empty, so Void Seeker cannot be played while the triggered ability is on the chain.

Sequence:

• Blastcone Fae is played from hidden
• Its triggered ability goes onto the chain
• The chain (and the ability) resolves completely, applying -2 to the target
• Only after the chain is empty can an action like Void Seeker be played

Nuances:

• If targeting Deadbloom Predator with the -2 ability, you must pay 1 power for deflect
