Card Rulings talk:King of the Swamp
Out of Date[edit]
There is an E-mailed Ruling that states:
- "You must have at least 1 Polymerization in your Deck or else you cannot activate the effect of King of the Swamp."
This makes the following ruling invalid:
- You can activate the effect of "King of the Swamp" even if all 3 of your "Polymerization" cards are in your Graveyard.[Update 1]
The evidence can be found from the e-mail from Konami.[Update 2]
