|Yu-Gi-Oh! Card Singles - Tip Card |
Effects that allow you to search your Deck are very useful. You can not always have "The Heart of the Cards" and draw the card you need. Sometimes you need to use a card effect to help you out.
Cards like "Sonic Bird" and "Senju of the Thousand Hands", "Giant Rat", etc, let you get more cards out of your Deck and into your hand or onto the field, which is always a good thing.
Even if you can not use the card you get with "Sonic Bird", etc., right away, this prevents you from drawing it during the Draw Phase when you cannot use it. For example, if you do not have a Ritual Monster and Summon "Sonic Bird", you can get the Ritual Spell Card anyway. It will not be useful until you draw the Ritual Monster Card, but if you drew the Ritual Spell Card then you would not only have a card you could not use, you also would have wated your draw to get it. Using "Sonic Bird"'s effect lets you avoid this. If you do not draw the Ritual Spell Card, you still benefit from having a compressed Deck.
