Koraidon also gets to benefit from Rainbow Cave! Cave + Sada gets Great Tusk attacking turn 1, making this list much better than before. This list commits to this strategy fully, and as a result cannot use Arena of Antiquity. (Which is ok, as long as Great Tusk can attack turn 1 to apply early game pressure with its high damage). This list has 3 really high HP Pokémon, so games will be LONG, meaning no arena is mostly a non-issue. Klefki is here so the chances of leading Koraidon are lessened.
