That may be too good, but I'll let it sit for now. G/W is supposed to have the strong creatures anyway.

The noticeable change here is that I switched from gem counters to ion counters. I figured, the fantasy world was already familiar with "ion stones" being little rocks that float around someone's head and gave them abilities, so it wouldn't seem weird. Meanwhile, having ionic charges of colored mana that twist around a creature's body gives a nice visual, and seems like a natural way to show creatures sharing their 'charges'.

I like that idea. It would come out nicely in art, like the Darksteel orbits (e.g. Darksteel Plate).

About the ability: shouldn't it be "As long as ~ has a counter on it, ..." so that it's a continuous ability rather than a triggered ability? It would make more sense, since it grants a continuous ability.

Yes it should. Thank you... I have a tendency to forget that "if" is a trigger.

Er... FWIW, "if" isn't a trigger. Triggered abilities have "when", "whenever" or "at". Always. "If" is generally only used as a condition inside triggers, as in the "intervening `if' clause". But yeah, "as long as" is right here.

Also, I do like "ion" for the counter name.
