I think that would be a wise move, although it does break the parrot theme of recasting stuff even if it was played on an earlier turn like the rest of them.
If they didn’t put in the “this turn,” which basically just makes the parrot a one time 3/3 brann, I’d personally put a cap on how expensive the battlecry could be… Like Repeat the last battlecry you played that costs 5 or less (original cost like the mage parrot).
It only costs 3 mana, why it can repeat 10 cost battlecries is beyond me.
