Weak against cards that DESTROY, TRANSFORM or DISPEL. If you are having trouble against Songhai include or add more of these to your deck:
Neutral :
Dispels- (Ephemeral Shroud, Lightbender),
Zenrui the Blightspawned, Repulsor Beast(Situational, only stalls), Primus Fist(Buff up a minion so that they only draw 1 Phoenix Fire)
Lyonar: Martyrdom, Decimate
Songhai: Onyx Bear Seal(situational, might want to keep for larger threats)
Vetruvian: Siphon Energy, Entropic Decay
Abyssian: Nightsorrow Assasin, Ritual Banishing
Magmar: Natural Selection, Eggmorph(Situational)
Vanar: Chromatic Cold, Aspect of the Fox, Bonechill Barrier/Gravity Wells(Situational, only stalls but prevents draw as the Lantern Fox receives no damage)
All classes have Artifacts that can buff them up to 4 ATK(Some situational) which can limit Lantern Fox to a single Phoenix Fire Generation.
