1. Why Balanced 4-Card Decks Beat Full-Top-5 All-DPS Lineups

In Extreme Demon Gacha Duels, raw AREDL rank is not enough if your cards never reach their Ultimate cooldowns before getting burst down. Adding LIMBO (Amplifier) funnels +25 flat Energy and +20% SPD on Turn 1, while Avernus or Silent clubstep (Break) shatters enemy shields to open a 1.5× Stagger window.
