In context with what it represents, I'd say a protection effect, quick effect board wipe (at a decently steep cost) and maybe some floating would be suitable...if you wanted to go crazy, you could also give it a passive board wide level amp of about 3 or higher (benefits shining sarc cards and screws with opponents boards) alternatively, it could "steal" levels, lowering opponents levels while giving them to your cards by the total lost. But I'm too lazy to write that in the official format, but what do you guys think?
