Before getting into the rules let me just say this format is not meant to go "try hard" and build the most optimal competitive deck to face off against your opponent. The idea of this format is to keep it casual and run those "bad" Knights of Atlantis, Chazz (Ojama/Armed Dragon/VWXYZ), God Cards and many other casual decks. Basically approach this format as if you're playing on the playground and not at a local game shop for a tournament.
This format was also designed to be used with the Duel Disk toys licensed by Konami. YOU DO NOT NEED A DUEL DISK TO PLAY THIS FORMAT.
Due to this format being made with the Duel Disks in mind there are rules in line limiting certain cards that can't be used with a Duel Disk.
1-Other than the following rules, all other official TCG rules apply.
2-Due to this being made for a Duel Disk XYZ, PENDELUMS, and LINK MONSTERS ARE BANNED!
3-All cards except for cards on this list are limited to 1 copy per deck and Extra Deck. This means you can play things like Pot of Greed.

4) Other than Xyz, Pendelum and Links no other cards are banned, but to balance Gameplay there is a tier-list
You can only have
3 Cards on the A Tier List
5 Cards on the B Tier List
10 Cards on the C Tier List
In your deck.

5)You can Normal Summon in face up defense like the Anime.
6) You can have up to 30 cards in the Extra Deck.
7) If a card would do something to a monster in the "Extra Monster Zone" it would apply to any monster special summoned from the Extra Deck instead. (EXAMPLES: Beatraptor, Chineratech Megafleet Dragon) (edited)
