If properly used, it can simply use the many ways it has to Special Summon from the Graveyard to provide material for Synchro Summons, not necessarily having to rely on big plays.
== Weaknesses == Infernities, despite their enormous potential as an [[Instant Synchro]] deck, have a number of crucial weaknesses. Of course, the foremost one is the one shared among most of today's competitive decks. Cards like [[Royal Oppression]], [[Macro Cosmos]], [[Dimensional Fissure]], [[Crevice Into the Different Dimension]] and any other that could lock down the main assets of the deck are the most dangerous threat, with [[Skill Drain]] placing just after them in terms of threat. Side-Deck [[Imperial Iron Wall]] to combat against the removal cards, and [[Twister]] to deal with [[Royal Oppression]]. Cards like [[Effect Veiler]] and [[Battle Fader]] that can be activated in hand can give major surprise and/or lockdown to Infernity combo. Cards like [[Threatening Roar]] and [[Waboku]] can slow Infernity for a turn, allowing you to get a bit of timing to counter. Also, by themselves they are a fairly weak archetype, with the most powerful non-Synchro card, [[Infernity Destroyer]], being only 2300 ATK and without a strong enough effect. Hindering the key cards of the deck with [[Prohibition]] and the like can also disrupt their strategy dramatically, since this will leave cards in hand, stopping the effects of [[Infernity]] monsters. Infernity monsters are also severely affected by [[Consecrated Light]]. This monster prevents the Summoning of DARK monsters; therefore disabling Synchro-Summoning. Be careful, Dark monsters can be Flip-Summoned. [[Consecrated Light]] will only stall for a turn or two. And if you're looking for cards to side against Infernities, [[D.D. Crow]], [[Crevice Into the Different Dimension]] and likes shuts down any Infernity OTK move. The fact that this deck depends on having no cards in your hand can be a weakness itself. If you play a large number of cards and then your opponent plays a field-clearing card like [[Judgment Dragon]] or [[Black Rose Dragon]], you may find yourself painted into a corner. To keep this from happening, [[Infernity Guardian]] is a great defense since it can't be destroyed by effects. Use [[Infernity Force]] to bring back [[Infernity Doom Dragon]] and counterattack. Another weakness of an Infernity deck is that it can be completely shut down by [[Ambitious Gofer]] due to the fact that it takes advantage of an empty hand.LOL!
