When you get to Zosma Tower fight the enemy called Mysterious Shellfish to get a sword for Kalas called the Apocalypse Sword. Keep fighting them until you have about 25 of these swords.

Put them all in your deck along with a decent supply of armor cards (about 15 to 20) and some element based swords (around 10 or so) and a few healing magnus and finishers with 9's in them.

Quite often you should be able to get final straight sunrises, 5,000 damage often, and even do over 10,000 damage from time to time.

Pac-Man:

Combine the strawberry, cherry, orange, melon and apple cards.

Pac-Man will change his appearance to Pac Land and Pac Mania versions..
