This is GREEEAAAT I loved every card!

I'm being serious, you did an excellent work here! No wonder you said "I'm taking my time with this". Heck, I think I have no qualms about any of the cards, and I'm not saying this because this is an xmas post and I'm happier than usual to check it, it's truly very well done, with effects that actually make sense and are balanced by your opponent benefiting when needed, while others that at first glance seem pretty brutal, like that criminal's Killause's 2500 effect damage, are also well balanced by how hard it is to Summon the card itself and the no-Battle Phase clause. Peeeerhaps the only monster card I'd feel too scary is the bossu Santa, but eh, I wouldn't even call it overpowered, it's just very strong, and it's the boss! Lastly, there's a single card in the set that would worry me, which is the last one, Naughty and Nice List. Just imagine, your opponent with 5 cards in hand, if you control Santa that's 2500 damage, then discards lol. Then you summon little elf and bam, 3000 damage and discard, then you summon Deer and bam, 3500 damage, game LOL.

Anyway, awesome work, Zama, and this time you can ask for a hint in the Xmas Development Thread for any of the Cards at the top that haven't been revealed!
