Karagon, Blossomer of Nature

Whenever you tap a nontoken druid for mana
add {g} or create a 1/1 green druid creature
token.
{3}{g}{g} : Tap 5 untapped druids you control,
search your library for a druid and put it onto
the battlefield. Then, if you control 8 or more
druids, double the amount of mana in your mana
pool and draw 2 cards. This mana may only be
spent to cast druid spells.
