Any cards that you draw are added to your hand. The normal [[hand size limit]] is six, so during your [[End Phase]] if you have more than six cards in your hand, you must [[discard]] cards until you have six cards left. [[Hieroglyph Lithograph|Some]] [[Infinite Cards|cards]] are able to increase the hand size limit, while [[Enervating Mist|others]] [[Silent Wobby|can]] decrease it.
A well known term, "Hand Advantage", refers to a deck's ability to perform strong combos while maintaining a good number of cards in hand should their plan fail or should they require extra cards to sustain their plan. For example, "[[Gadget]] [[Xyz]]", "[[Qli]]", "[[Junk]] [[Synchro]]" and "[[Harpie]]" decks contain many cards that can maintain hand advantage.
Certain card effects can interact with cards in players' hands. For example, "[[Spirit Reaper]]" can [[discard]] 1 card from the opponent's hand as part of its effect, and "[[Exchange]]" allows you to swap one card from your hand with one card in your opponent's hand. Many card effects have [[cost]]s that require discarding a card(s) from your hand, such as "[[Raigeki Break]]", and you cannot activate such effects unless you have enough cards in your hand to [[pay]] the cost.
