As always, happy hunting!
When an opponent's Spell/Trap Card, or monster effect, is activated that targets a "Frightfur" monster(s) you control: Negate the activation, and if you do, destroy that card, then you can send 1 of the targeted "Frightfur" monsters to the Graveyard, and if you do, Special Summon 1 Level 8 or higher "Frightfur" Fusion Monster from your Extra Deck
While it seems a bit bland, the simplicity of this card is what makes it so good and desirable
Its also a human and cleric for the decks that want those types of creatures, and protection from white helps in a lot of matchups
