Diachronos

:: Kyroceanar is kind of a "filler"; I didn't really know what I wanted to put in that slot, so I decided to just use him. Ice Beam is standard for my Water-types (as Grass protection), and Earth Power makes a good substitute for Earthquake due to Kyroceanar's high Special Attack. Muddy Water is a replacement for Surf, since hurting the other party members isn't a good idea in the Courtyard Colosseum, and Thunder is there just to take advantage of {{a|Drizzle}}.  

* Deoxyribot- Deoxys (Defense Form), shiny

::Deoxyribot replaces the Attack Form Deoxys I was using previously (Deoxyribos; for some reason he couldn't dish out as much damage as he should have). His high Defense stats combined with Recover and the Leftovers make him hard to take out, and Aromatherapy virtually eliminates the threat of status conditions. Since I'm bad at guessing what kind of move the opponent is going to use, Counter and Mirror Coat don't do damage very often, but they pack a hell of a punch when they connect.
