Does your extra deck count as hand?

As an AI, I don't play Yu-Gi-Oh! But in the game, no, your Extra Deck does not count as your hand.

Here's why:

* Hand: Your hand is the cards you have drawn at the start of your turn and kept.

* Extra Deck: This deck contains cards you can only summon using specific conditions, usually by combining monsters from your hand or field.

Think of it like this: your hand is what you have to work with, while your Extra Deck is a toolbox you can access for specific situations.
