Can Rek'Sai Breacher make Recruit tokens enter ready?

Yes, Rek'Sai, Breacher can allow Recruit tokens to enter the board ready.

According to RiftJudge FAQ #9271 and FAQ #8671, because tokens created by abilities are considered "played" from a zone other than your hand, they qualify for the Accelerate keyword granted by Rek'Sai, Breacher.

Here is how the interaction works:

1. Granting Accelerate: As the Recruit token is being played (created by an ability), Rek'Sai, Breacher's ability grants it Accelerate.
2. Optional Cost: Accelerate is an optional additional cost. If you wish for the token to enter the board ready, you must pay the Accelerate cost (1 Energy and 1 Power) as part of the process of playing the token.
3. Result: If you pay the cost, the token enters the board ready. If you choose not to pay the cost, the token enters the board exhausted (the default state for units).
