I added an 'activate this ability only once each turn' to the metaphysic mechanics. This is to prevent infinite combos with cards like shuko. The only trouble is that this sentence doesn't seem to work here, since atomistic metaphysic (as well as the others) isn't an activated abilities as far as I can tell. It may be a triggered ability, I'm not certain. But if it is, I have no idea whether a sentence like 'trigger this ability only once each turn' or 'this ability can be triggered only once each turn' is meaningful.

How about "The first time this permanent is targeted by a spell or ability each turn..."

Yes. You want to use the template as on Jetting Glasskite or Kira, Great Glass-Spinner.

"Whenever this creature/permanent becomes the target of a spell or ability for the first time in a turn, ..."

Cool, thanks guys!

Love this artwork. :D

I agree, this is fantastic.

I wish I could take all the credit for the artwork here, but Mrs. Putnam is responsible for the card concept and for drawing the guy with the kerchief.
