Id certainly pay four life to have repeatable Solemn Simulacrums every turn
We're planning to expand the range of cards that can be traded
The random-mix rule A random selection means the mix can vary across Pokemon, Trainers, set eras, artwork popularity and market liquidity
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
Why is this done
For seven life, Griselbrand lets you draw seven cards, refilling your hand and probably causing you to discard cards at the end of your turn to put another reanimation target into your bin
