Can you use Repeat on Hard Bargain after it's already been put on the chain to target a second spell?

Ruling: You cannot use Repeat after Hard Bargain has been put on the chain. You must decide when initially playing Hard Bargain whether to pay the additional cost for Repeat.

Sequence:

• When playing Hard Bargain, decide whether to pay for Repeat
• If you choose Repeat, you can target the initial spell (forcing higher cost to avoid cancellation)
• You cannot add Repeat retroactively after the spell is on the chain

Nuances:

• If you Repeat Hard Bargain targeting the first spell, the opponent would need to pay more to avoid cancellation, but if they have a backup spell, the Repeat may not help
