- Gain one random mutation.
- Lose one random mutation then gain one random mutation.

Power level 1: If there are no mutations, gain one (likely to be good). Otherwise, with equal probability:
- Gain one mutation (likely to be good mutation)
- Lose one mutation (likely to be bad mutation if the player has any bad mutations).
- Gain one mutation and lose one mutation, with following probabilities:
  - 25%: Lose one probably-bad mutation and gain one random mutation.
  - 25%: Lose one random mutation and gain one probably-good mutation.
  - 50%: Lose one random mutation and gain one random mutation.
Power level 2: With equal probability:
- Lose a probably-bad mutation; no effect if there are no mutations.
- Gain one probably-good mutation.
- With equal probability:
  - Lose a probably-bad mutation if the player has any, then gain a random mutation.
