If you control creatures other than Mistbreath Elder as its triggered ability resolves, you must return one of them to its owner’s hand. If you don’t, you have the option to return Mistbreath Elder to its owner’s hand or leave it on the battlefield and have the ability do nothing.
At the beginning of your upkeep, return another creature you control to its owner's hand. If you do, put a +1/+1 counter on this creature. Otherwise, you may return this creature to its owner's hand.
