Verdant Kodama

Verdant Kodama is pretty good if you use her right, but that means not using her with dark locations. 50% ToD is underwhelming compared to free second life and auto-healing. Melrak Assassin gets 50% ToD for 1 less mana, with a better stat skew and real synergies, and doesn't need you to play a dark location before he does it. Killbot gets 100% ToD (against 93% of all monsters) for about the same amount of mana, and again doesn't need a dark location.

I guess you could say she's intended to be used with light and gray locations, and having any ability at all in dark ones is a small bonus, for when your opponent drops one you can't replace right away, but it would still be nice if her dark ability was a little more useful.
