Slimey Disposition (SBC1-ENS16)

Once per turn, you can Special Summon 1 "Humanoid Slime" or 1 "Worm Drake" from your GY in Attack Position, but it cannot be Tributed, except for the Tribute Summon of a Divine-Beast monster. Once per turn, you can discard 1 card, then Fusion Summon 1 "Humanoid Worm Drake" using either "Worm Drake" or "Humanoid Slime" from your field as 1 of the Fusion Materials, and the other material from your Deck.
