Infyrana is loaded with special powers. First of these is that she is a dragon (by her title), allowing her access to the dragon-only spells and unarmed combat cards. This power also allows her to be targeted by cards that do bad things to dragons of course. Next is Infyrana's power of being a flyer, giving you access to attack realms in the rear of your opponent's formation(s). The most powerful of her powers are the immunities to Heroes and allies, this includes all allies, not just allies of heroes.

Infyrana is immune to the 'special powers' of heroes, not heroes themselves, so your opponent's heroes can still face her in battle. Being the only non-avatar immune to Gib Kcir [RR-c16] is a good thing (though being immune to Bahamut [DR-45] is not)! What makes this champion great for combat decks is her immunity to allies coupled with the avenging power of discarding a magical item or artifact if she is discarded in battle. Your opponent's The Winner's Cape [4th-520] would be a great choice to use this power on. All in all, Infyrana is a great choice for a wide range of decks. From dragon themes to combat to even tournament decks.

With all of this card's powers you would find many uses for her. If you intend to use her, you also might consider using Dragon Mountain, which boosts Infyrana nicely if she defends it. If Infyrana is in your deck, you may want to add Dragon Mountain. When Infyrana defends Dragon Mountain, its base level is doubled to 16.
