Fyrakk the Blazing is missing an Elemental tag, which doesn’t feel consistent when looking at cards like Volcanosaur and Charged Devilsaur who are half-Elemental because lore-wise they’re gorged on Elemental energies, which is exactly what Fyrakk is.
While most Dragons in Hearthstone aren’t Elementals even when having a lot of Fire, Frost, Water, etc. on their bodies, Fyrakk - and the other Primal Incarnates for that matter - are specifically much more charged in Elemental energies. Iridikron’s appearance is near-identical to the card Stone Drake, which has the Elemental Dragon dual-type, Fyrakk and Iridikron are similarly over-gorged on Elemental energies, so Fyrakk the Blazing should logically be an Elemental Dragon.
