Gryrro, the Egg

Familiar (Starts outside the game face up. Can't be
cast. If it would leave the battlefield, exile it instead.)
At the beginning of your upkeep, if you niether control this card nor a Dragon, put this card from outside the game onto the battlefield under your control. If you do control this card, put a +1/+1 counter on it and then, if it has two or more
counters on it, exile it, and put Gryrro, Inquisitive Dragonling you own from outside the game onto
the battlefield under your control.
