1-Other than the following rules, all other official TCG rules apply.
2-Due to this being made for a Duel Disk (again you don't need one) the following summoning types of cards are banned from TikTok Format Tournaments for the following reasons:
Xyz Cards-Due to stacking multiple cards being difficult to do as well as Duel Disks damaging cards as is Xyz cards are banned.
Link Cards-Due to Duel Disks not being equipped with an Extra Monster Zone link cards are banned.
Pendulum Cards- Without Link Cards keeping Pendulums in check like in the TCG Pendulums would run rampant in this format and are banned.
3- All cards are limited to 1 copy per deck EXCEPT for cards on this list, you can play 3 of anything on this list: https://tinyurl.com/AnimeFormatExceptions
4) Other than Xyz, Pendulum and Links no other cards are banned, but to balance Gameplay there is a Tier List: https://tinyurl.com/tiktoktierlist
You can only have
3 Cards on the A Tier List
5 Cards on the B Tier List
5)You can Normal Summon in face up defense like the Anime.
6) You can have up to 20 cards in the Extra Deck.
7) Cards that have a (this card is always treated as "card name") can be ignored.
Example Harpie Lady 1, 2. And 3 are always treated as the original Harpie Lady.
In normal ocg/tcg you would have to choose the ratios from amongst them to play.
But here you can run the 3 original and then 1 of each other effect harpie.
Another instance of this is "Umi" and card like "A legendary ocean"
