Power: High Rogue (8.6/10) - Legal Link Evolution Endymion Spell Counter. It loses banned Apollousa and Abyss Dweller, but the Endymion/Mythical Beast core is still explosive, searchable, and backed by real spell-counter negation.
Consistency: Excellent. Spell Power Mastery, Servant, Master Cerberus, Mythical Institution, Citadel, Spellbook Magician, Secrets, Knowledge, Desires, Upstart, and Terraforming keep spells flowing and counters building. The risk is opening too many payoffs without enough spells.
Ceiling: Very strong. Mighty Master, Jackal King, Reflection, Secret Village, Selene, Vortex, Norito, Avramax, Unicorn, Borrelsword, and Big Eye give layered disruption, bounce removal, spell lock pressure, and finishing power without illegal Extra Deck shortcuts.
Recovery: Strong. Pendulum mechanics reload face-up monsters, Citadel stores counters, Institution searches follow-up, Selene revives Spellcasters, and Endymion can reset cards while putting itself back into scale.
Going first/second: Stronger going first with Servant or Mastery into Endymion/Jackal King plus Village or Selene. Going second, counters become removal through Endymion, Reflection, Garuda, Phoenix/Unicorn, Big Eye, Borrelsword, and side breakers like Nibiru, Cosmic, Twin Twisters, Duster, and Evenly.
Choke points: Stop Servant before it places three counters, remove Citadel/Institution before they snowball, Ash Mastery or Spellbook lines, or force Endymion negates before the deck has enough counters to rebuild.
Key cards: Endymion, Servant, Reflection, Magister, Master Cerberus, Jackal King, Spell Power Mastery, Mythical Institution, Magical Citadel, Selene, Secret Village.
Key combos: Mastery finds Servant and loads counters. Servant spends three counters to summon itself plus Endymion, Jackal King, Magister, or Reflection. Spellbook Magician plus Secrets/Knowledge adds spell volume. Selene revives a Spellcaster for Unicorn, Avramax, Borrelsword, or more Endymion pressure.
