Card Trivia:Arcana Knight Joker
- This card is similar to Royal Straight Slasher in appearance. It also needs the same monsters to summon.
- "Arcana Knight Joker"'s cost for using its effect is based on Matching.
- i.e. "Enemy Controller" targets this card (chain link 1) then AKJ effect can activate as (chain Link 2), but B4 chaining its owner must discard a magic card as a cost to activate this card's effect because "EC" is a MC and MC=MC. This card's Quick effect also applies to Effect Monster's effect and trap cards.
