For Get Excited, when do you declare the target and when do opponents know how much damage will be dealt?

Ruling: You must declare the target when Get Excited is put on the chain, but you don't discard until it resolves, so opponents won't know how much damage will be dealt until resolution.

Sequence:

• Get Excited is put on the chain and you declare the target
• Opponents can respond, but don't know the damage amount yet
• Get Excited resolves, you discard a card, and damage is dealt instantly

Nuances:

• All effects that target must declare targets when put on the chain
• The discard cost is paid on resolution, not when targeting
