Archdruid

Hexproof
Whenever a creature enters your battlefield, you
may have it become a 3/3 Bear with Trample,
1/5 Bird with Flying, or a 2/2 Wolf with
Prowess. If you choose not to, put two +1/+1 counters on it instead.
If you are the Monarch, those creatures also keep
their original types and abilities or put an
additional +1/+1 counter on that creature.
