Flash Escaveil
LIGHT/Level 3
1200/1000
[Thunder/Effect] Once per turn, you can discard 1 "Flash" Monster: send 1 "Flash" Monster in your deck to the Graveyard. When this card declares a direct attack, return all "Flash" Monsters in your deck to the Graveyard: Increase the ATK of this card by 800 for each returned "Flash" Monster until the end of the Battle Phase.

Sand Demon Gomorroth
Level 4/EARTH
1600/1000
[Reptile/Effect] During your Standby Phase, increase the ATK of all EARTH Reptile-type Monsters you control by 500, and decrease the ATK of all face-up non-EARTH Reptile-type monsters your opponent controls by 400. When your opponent takes battle damage, increase the ATK of all EARTH Reptile-type monsters you control by 400.

Insistent Illusion
Level 4/LIGHT
1400/1700
[Psychic/Effect] When this card is Normal Summoned, add 1 "Insistency" from your deck to your hand. When "Insistency" is activated while this card is face-up, negate the effects of all Spell, Trap and Monster card effects your opponent controls until the End Phase. If this card is selected as an attack target, you can send 1 "Insistent" Monster you control to your hand to negate the attack and inflict 800 damage to the opponent.

gomorroth seems really slow and doesn't help the archetype very much

escaveil returning all flash from grave to deck is entirely counterproductive. maybe only 1 at a time to recycle serpents or a milled phoenix
