Ukaran Beastwatcher

Trample
Roar- Whenever you cast a creature spell with converted mana cost four or more, Satyr Beastwatcher gets +X/+X until end of turn. Where X is the number of Beasts you control.
The satyr sat behind a tree watching a few beasts play in the dirt. He silently wished that he could be one of them. Sadly, only Sauruk had discovered how to transform from one animal into another.
