Rune-Clad Druid

Rune-Clad Druid comes into play with a Rune
counter on it.
Whenever a Druid, Beast, Elemental, plant,
Wurm, or Dinosaur creature comes into play, put
a Rune counter on Rune-Clad Druid.
Remove a Rune counter from Rune-Clad Druid: Creatures you control gain +2/+2 until end of
turn. Add {g} to your mana pool for each
Druid you control.
