Blessed by the Wilds

Whenever you tap a creature you control for
mana, put a ritual counter on Blessed by the
Wilds.
Remove five or more ritual counters from Blessed
by the Wilds, then sacrifice it. Create a 1/1 green
elf token with "{t}; Add one {g}" for each ritual
counter on Blessed by the Wilds.
"The elves learned long ago. If you give to her.
She'll give back."
