You can use this card to protect important cards in your hand, like pieces of Exodia, especially from X-Sabers.
This card allows you to benefit from the effects of "Infernity" monsters without actually having to get rid of all the other useful cards you would otherwise have to discard to the Graveyard. This means you no longer need to rely upon cards such as "Full Salvo" to dispose of your entire hand, and you can save cards for later use.
Although a full hand goes against an "Infernity" deck, by using this in conjunction with "Morphing Jar" when you hold a moderately sized hand, you can draw your key cards faster and disrupt your opponent's strategies, as long as you don't need to use your Infernity's effects for a turn or two.
You can use "Yamata Dragon" since every turn your hand is treated as you had 0 cards,so every turn you would draw 5 cards.
You can use this card in conjunction with "Dark World Grimoire" as you can bypass the 6-card hand limit until you have the right monster to discard.
You can use this card to work around the hand limit, and then discard in conjunction with "Forced Requisition" to devastate your opponents hand.
This card works exceptionally well with Infernity Guardian, creating an indestructible shield once per turn.
