Can you accelerate a creature played by Baited Hook?
Yes, you can pay the Accelerate cost when playing a unit via Baited Hook.
According to RiftJudge FAQ #5335 and #7120:
- Baited Hook only sets the base cost of the unit you play to zero.
- Optional additional costs, such as Accelerate, remain optional and can still be paid. If you choose to pay them, the unit will enter the battlefield readied as per the Accelerate keyword (Rule 805.1.a).
How it works:
- You resolve the Baited Hook ability, which allows you to play a unit from your deck.
- During the process of "playing" that unit, you are presented with the choice to pay its additional costs (like Accelerate).
- If you choose to pay the energy and power required for Accelerate, you pay them, and the unit enters the battlefield ready.
