Welcome to Djinn Nekroz meets Tramids.
This DARK archetype based on fear itself is very Field Spell focused, with several different ones that it has access to . . . each with exactly 3 effects. Why 3? Because they also have a terrible trinity of Ritual bosses based on the grand-daddies of fear: Death, isolation, and fear itself. Each of these bosses has, as the first line of their effect text (except the whole Ritual Summon conditions thing), "This monster gains the (insert number here) effect of all "Terriform" Field Spell Cards in your Graveyard". Of course, this means that "Terriforming Entity of Inherent Terror" can (fittingly) Ritual Summon the other two bosses . . . because, surprise surprise, they have a Field Spell that can do that. Their archetype is actually surprisingly consistent, too, given that they have an Orphrys Scorpio, a Stratos, multiple pseudo-Shurits . . . And their Ritual Spells can banish themselves to search each other, and when they do, something else happens.
Then, of course, while the terrible trio are their big bosses, they aren't their only Rituals, and you get all kinds of powerful effects among them . . . including one that acts as a one-sided Necroface, taking away all the penalty of banishing your Ritual Spells.
Then, the Field Spells . . . utterly hate your opponent getting to play YGO. Stat boosts, protection, locking out the ED, standing in for Dark Law, Malefic World, Geartown, Chain Energy, automatically hitting each player with Card Destruction during their Standby Phase . . .
Do you fear power? Terriform breathe it. They feed on it. They love it.
CnC would be appreciated! :D
