Can you play Get Excited onto the chain, then play Gust to return Flame Chomper to hand, and discard it to Get Excited (allowing you to replay it)?

Ruling: Yes, this works. The discard cost for Get Excited happens at resolution of the spell, not at cast, so you can return Flame Chomper to hand with Gust before Get Excited resolves and then discard it to satisfy Get Excited's cost.

Sequence:

• Play Get Excited onto the chain
• Play Gust, returning Flame Chomper to hand
• When Get Excited resolves, discard Flame Chomper to satisfy its cost
• Replay Flame Chomper to the battlefield

Nuances:

• During combat, control of the battlefield doesn't change, so you can replay Flame Chomper to the battlefield even if it would otherwise be empty after Gust resolves
