First Heart: You and Syrus tag-duel against Chazz and Jesse
Unlike regular packs, these cards aren't about game-changing pulls or competitive play but more about celebrating Halloween with a collectible twist
some of these, to my knowledge, need some minor rewording to be a bit less clunky to read but other than that i'm really into the different effects and gimmicks, if you wanted to dip your toes into alchemy a bit I'd suggest a platinum as a potential boss monster (since you already used silver, the metal of the moon), either as a fusion of gold and silver (the alchemical symbol for platinum is literally just the gold and silver symbols next to each other because it was believed to be a composite of the two) or a rank 3/4 Xyz, possibly one with a sort of reverse gemini effect that makes it a normal monster when it runs out of materials, maybe a level 1/2 "moonfang ore pup" that can SS one of the others either on death or by self sacing
Discard lands if you have enough mana, discard spells to grow your creature, or discard reanimation targets and madness cards for additional value
The other is the Deck Leader concept
Rarity Levels Just like other trading card games, Lorcana cards have different rarity levels
