Hydra River Head

Hydra River Head comes into play tapped.
It does not untap during the first untap phase
after it enters play.
{t}: Add {c}{g} or {c}{u}.
Deep in the vast forest og Grolm lies the many heads
of the Hydra River. A Titan wandered the forest,
each night summoning an earth dragon to bring a
torrent to the surface to quench its thrust. They
gush still, uncounted in concealing forests.
