[YU-GI-OH's - All Series] Why do the duelists explain the rules and effects of each card to each other in battles, wouldn't they already know all this being top tier players?
gpt
There are a *lot* of cards. And the top tier players have some rare cards that they don't want **everyone** knowing the secrets of. 


And a lot of the time, they are explaining how their card combos with another card, another thing they don't necessarily want to advertise before they use it, because it just makes it that much easier to counter. 


And of course, there's Pot of Greed, and who can even remember what that does?
