Hilarious!
It reminds me of old-school Yu-Gi-Oh where you have to use like Polymerization to get your Fusion summons or something?
So for me this is a whole card type.
Forged cards can be gained but not bought. Each player has their own Forged pile (I guess like a personal Prizes pile kinda, so it doesn't count towards three-pile endings) to gain from, with cards they picked.
Very Yu-Gi-Oh
This one is two Weavers forged together, since I thought "gain four Silvers" would be funny.
