Remember, the list works differently in Duel Links than it does in the TCG/OCG. You can only run 1 Limited Card period, not one of each, here. A limit-to-3 would work the same way. You can only run 3 cards total of all the cards that are limited-to-3.
Correct. In fact, a lot of our Semi list currently is mostly to prevent the stronger decks using cards like Enemy Controller and Treacherous Trap Hole by semiing deck-critical cards like Iron Core of Koa'ki Meiru.
so how the limited 3 works is basicly like this: i have blue eyes, dark magician and red eyes, all of which limited 3. if i put one of each in it's okay, but putting another copy of one of these cards is not allowed, correct?
