@role 10/26 UPDATE [Please do not vote in the next 20-30 minutes]
HALLOWEEN EVENT (2 weeks long from TODAY)
Now this will be slightly more complicated than usual. There's 4 new commands with the Halloween event and 4 new cards - 2 of them are going to be used as fodder.
The Halloween event exclusive cards will not be available in packs/drops, and will appear very rarely in raids.
Instead, there are 2 new fodder cards. Skeleton cards are used to make Sans, the popular Undertale character, while Ghost cards are used to make No Face from Spirited Away. These cards can be dropped by packs, claims, raids, etc.
.treat / .trick command - Only 1 of them can be used in a 2 hour process. Treat provides you with a consistent 5 fodder cards (Skeleton/Ghost cards) to be used in .merge, while Trick provides more RNG. Please do .help treat /.help trick for more information about the rates and what it gives.
.merge - this is a unique command that takes in 50 Skeleton/Ghost cards to make Sans/No Face. The higher rarity your sacrifices are, the more chances of you getting a SR/UR. If you use a SR Ghost/Skeleton as one of the materials, it will be guaranteed to be SR+, and if you use a UR Ghost/Skeleton as one of the materials, it will be guaranteed to be a UR.
[Example] .merge skeleton / .merge ghost -> merges your LOWEST 50 rarity cards of Skeleton/Ghost to create a Sans/No Face card of a rarity determined randomly based on the rarity of the cards.
[Example] .merge skeleton 74 -> Merges your LOWEST 50 rarity cards of Skeleton, but includes the inventory ID 74 Skeleton card as well for merging. This is useful if lets say, you had a SR Skeleton card (ID 74) that you can put inside the merger so it guarantees a SR Sans.
More information can be found in .help merge.
.rd spspawn spawns a random Ghost/Skeleton card for a Raid.
