The instosis deck was already overpowered, but this just takes the cake :p As soon as I saw shard of bravery, I knew this would happen. I already proposed some nerfs to that shard, so I won't repeat them.
The other problem I will discuss is the (I'm assuming) unintended effect by which multiple SoRs on the same creature allow even more skill uses/turn. Spamming SoR on a time creature shouldn't let you use the ability more than twice in the same turn. The card says 'time creatures may use their skill twice this turn'. If you play a second SoR on a creature that has already used its skill twice this turn, why are we allowed to use it -another- two times from a second SoR? Changing that one thing would fix Instosis from being such a powerhouse. (heck, it would make the deck unplayable)
