There weren't any caps (and using any other resourses than the ones of selected prep base is impossible according to rules. And Spot by himself is less dangerous than say Blink- redirecting stuff at your opponent via portals is one thing, have enough skill to do anything sophisticated with that is another.
His portals are at least visible (unlike some stuff that can be (and there's a degree of probability) seen only by 2 people out of the whole tourney roster.
Some amalgams might be scary, but there's no cap on amalgams.

By the way, I want the opinion of judges on one thing. If the ability of selected char which is banned by the rules is dormant via self imposerd mental blocks at the state people take the char, but can be activated by amalgamation\another means during the prep, how should the char be treated?
I'm talking about Sage. She has her telepathy turned into defence mode, but if Synch copies her powers, he'll copy them without the mental block (he managed to copy Emma's latent telekinesis once). That's really a tricky case.
