MC - Typos, confusing ability text, grammer etc

Yeah, 'library' is entirely new to Switcheroo, and non-CMC terminology (stolen from M:tG). Could make newbies think that Ivory Libraries only contain a certain number of cards, which would be really misleading. Wants to be 'decks' instead.

'Attaches to own' simply means the modifier can only attach to your own entities, and not those of the opponent. The three cards that use this already use four lines of text, so it can't really be expanded upon. But they all use short Modifier Types (device and robot), so it would probably be possible to change the type to 'Attach robot to own monster'. This probably isn't any more easily understandable though, and could be problematic in the future for attaching longer Modifier Types. Probably no solution, so best left as is unless someone can think of something?
