That first ability is currently mono-white. If it didn't say "attacking" creature then it'd be either or mono-. But I think you're trying to use it as the option, and it's not .

Interestingly, my goal with the cycle is to have both options be something the primary color could theoretically do alone, which is stronger when combined with either of the other two colors. I saw both abilities as things that could be costed or . You're right that the attacking restriction makes it too white, though, I guess.

Call me old-fashioned, but it's not a charm. It's just a basic modal spell. Charms need 3 abilities, and this ain't it.

I acknowledge your concern over on Elemental Charm.

It's quite plausible that Wizards will at some point print a drain spell (I guess they already did with Death Grasp). I kinda hope they don't - I'd like damage-and-lifegain to stay either or mono- - but I suspect they will eventually. So yeah, I guess the first effect fits your hybrid aim. It's better now it says "tapped" rather than "attacking".

The second... I don't really know. It's got enough riders on it and the odd library location rather than destruction that I don't know quite where in the pie it is.
