Special Summons 2 Infernity monsters from the graveyard.
Can only use effect if you have no cards in hand.
Here are some of the Infernity monsters currently in the game which you can revive with Infernity Mirage's effect. Tuners like Infernity Beetle can be revived alongside another non-Tuner Infernity monster to make a Synchro monster of your choosing.
Like most Infernity monsters, Infernity Mirage requires you to control no cards in your hand to use it's effect. So here are some cards to help you with empty your hand, most these cards are specifically made to support Infernity monsters so you get additional benefits for clearing your hand.
It's less surprising when you look at the rest of the rewards. Other than this, Infernity Patriarch, and Infernity Inferno, not too many of the Infernity drops are worth running. They released decent support, but Infernities are missing the core aspects that made the archetype strong IRL.
