The Endymion promo finally makes their move.
VJMP-JP160 ローグ・オブ・エンディミオン Rogue of Endymion
Level 3 FIRE Spellcaster Effect Monster
You can use each effect among the (1)st and (2)nd effects with this card’s name only once per turn.
(1) If this card is Normal or Special Summoned: Place 1 Spell Counter on it.
(2) You can remove 1 Spell Counter from this card, then discard 1 Spellcaster monster; Set 1 Continuous Spell directly from your Deck, and if you do, you cannot activate cards, or the effects of cards, with that name for the rest of the turn.
And the accompanying V Jump YouTube Video:
They suggest to use it with Floodgates like Dimensional Fissure and Kaiser Colosseum.
