Sylvian Goddess of Love

Forestwalk (This creature can't be blocked as long as defending player controls a Forest.)

If one or more tokens would be created under your control, those tokens plus that many 1/1 green Tumor (S) creature tokens are created instead.

{b}, Sacrifice X Tumors: Target creature gets +X/-X until end of turn.

The green hue is starting to make you feel dizzy...
