Leafy

Whenever you draw a card, you may pay
{r}{g}. If you do, creatures you control get
+1/+1 until end of turn.
Whenever a source does damage to Leafy, Leafy
deals damage equal to the amount of damage
dealt to Leafy to that source's controller, and
Leafy gets +2/+2 until end of turn. Add {r}.
{5}{u}{r}{g}, {t}: Draw cards equal to the
number of creatures you control, then untap
up to 8 lands you control.
