1) It's fine that I'm now in game, but when loading/saving, computer goes sloooooooow
2) Kaiju is an archetype in the card game YuGiOh which revolves around tributing your opponent's monsters so that you can summon (generally) weaker monsters to their field, which allows you to summon a (generally) strong monster to your field. These decks generally don't summon monsters the normal way. A Mirror Match is when two decks of the same archetype battle each other. So, Kaiju Mirror Match is 2 Kaiju decks against each other, making it a game of "SUMMON SOMETHING" "I CAN'T!".
