Kaiba Corp current has a new 2 dueling format implented in the duel system.
KC Normal Play (Deck Slots 1-3): You are allowed to add up to 3 Banned cards to your deck to play with this format. Its mainly design for fun play and to reduce the abuse of tradition format by limiting the amount of banned cards you can use to 5 cards only.

KC Tournament Play(Tournament Slot): You are allowed only up to 1 Banned card People that enjoy advance format dueling will enjoy this as well as the little bit of random-ness of that 1 banned card possible.

The following Banned/Restrict list is similar to Konami's but I made a few changes here and there. Expect to see this list change every 2-3 months to keep things interesting.
