To draw a card (Japanese: ドロー Dorō) is to take the top card of your Main Deck and add it to your hand. Drawing a card is a form of "adding a card from the Deck". If "Blackwing - Breeze the Zephyr" was drawn by a card effect, then you can Special Summon it. Because of this, the card "Thunder King Rai-Oh" had to clearly make an exception in its lore, and the card "Drastic Drop Off" had to clarify that drawing is considered adding a card to the hand. Every turn during your Draw Phase, you normally draw one card from your Deck. The player going first cannot do this on their first turn.
