As ye vets should know, Leaf Dragons have activated skill
"Photosyntesis:
Gain
. This skill can be used multiple times per turn."
Quite simple enough.
Shard of Readiness on the other hand says
"The target creature's skill cost is now zero"
This would result in endless
quantum, yes?
However, when I realized the potential this had, and applied this in practise just to test if it would work, my leaf dragon reacted rathed peculiar way.
After introducing the Shard, I could use the now zero costing skill only once per turn, even tho the "card" still had it's function text on it.
I believe Rustlers react the same way.
Bug or Feature?
