Lineup: Eraser Cat, Crazed Wall Cat, Catellite, two other anti-Alien Cats (i.e. Neo Psychocat and Castaway Cat), Thaumaturge Cat, Macho Leg Cat, Cyberpunk Cat or any other long-ranged unit, an anti-Alien Uber Rare/Legend Rare (can replaced by Valkyrie Cat) and Crazed Bahamut Cat/Awakened Bahamut.
Battle: Ursamajor and Maawth are the main problems, since they can outrange many cats, hence why you need a long-ranged cat. Rover Cat Mk II/Catellite is highly recommended as a meatshield thanks to its Warp Blocker ability. Stacking Macho Leg Cats and Castaway Cats helps kill Satan Claus fast, while Neo Psychocat Cat helps slow him down and keeps him from advancing too far. Valkyrie Cat is preferred over Ururun Wolf, as she can knockback Satan Claus, causing all your cats to walk into Ursamajor and Maawth's range. Crazed Bahamut Cat can be used to kill any enemy here because he outranges all of them. Good luck!
Strategy 2 (Speedrun/Farming)
Lineup: As many Worker Cat Lvl Up and Starting Money Up Cat Combos as possible. (I used Lingerie Special, Bouncing Four, and Duet Cat Combos). You must have Crazed Giraffe Cat (20) and Awakened Bahamut Cat (30). There are a few extra slots that you can fill with more rush units if you have them (Giraffe Cat/Lion Cat, Fishman Cat, etc.).
Battle: Don't upgrade your Worker Cat. Save up for Awakened Bahamut Cat, and send him out immediately. After that, send out Crazed Giraffe first, then spam your rushers. You can beat it before Satan Claus even appears.
