Iterating Suppress

Doing some brainstorming about how Suppress might work as it's fleshed out. It is kind of similar to detain or tap spells, but with a different feel that seems appropriate for Overgrowth's emphasis on growing creatures.

So I've reworded the text a bit and also made it so it can be both an end-of-turn effect or also an ongoing aura.

So to make it clearer in the rules, it won't affect any sort of power and toughness alterations that are endemic to the creature itself. That gives the mechanic a little bit of a weakness, but it also makes it more clear and avoids a lot of rules conflicts.

I do realize that using words like "unaffected" and "external" might cause some level of confusion. I want to make it clear that it doesn't destroy auras or equipment or even counters. They just don't "affect" the creature. And I think this wording sets it up that additional combat tricks or buffs in response also don't work. I think. This will obviously need to be playtested quite a bit.
