Koffing

Evolve now or wait
from the game's learnsets and the relearner ruleKoffing evolves at level 35. Nothing is lost by evolving straight away: every move Koffing learns after that, Weezing learns too.
Rule the game applies: the Move Relearner on Two Island (he takes two Tiny Mushrooms or one Big Mushroom) teaches only the level-up moves of the form you hand him, at or below its current level. Delaying an evolution costs the evolved form's higher base stats for every level you wait; a move you barely use is not worth that.
