For Convergent Mutation, if you copy stats from a creature with temporary buffs to another creature, does the copied creature keep those buffed stats after the original buff expires?

Ruling: No, the copied creature does not keep the buffed stats permanently. The card has a printing error and should read "until end of turn" according to the errata.

Nuances:

• For competitive play, the errata always takes precedent over what is printed on the card
