Power: High Rogue (8.9/10) - This is a Link Evolution card-pool Thunder Dragon Chaos build tuned for current TCG legality. It keeps Milim's explosive, destructive identity through Titan, Colossus, Levianeer, and the Thunder Dragon banish engine, but replaces illegal or outdated pieces with legal extenders and board breakers.
Consistency: Strong. Batteryman Solar, Aloof Lupine, Thunder Dragondark, Thunder Dragonroar, Gold Sarcophagus, Allure of Darkness, Pot of Desires, and Thunder Dragon Fusion give the deck many ways to start or reload. Black Dragon Collapserpent and White Dragon Wyverburster replace slower Thunder Sea Horse lines with more immediate Chaos pressure.
Ceiling: High. The deck can put up Colossus search pressure, Titan destruction, Levianeer hand or field swings, I:P and Knightmare lines, Borrelsword pushes, and Instant Fusion into Millennium-Eyes Restrict to protect plays or absorb a monster effect. It is still High Rogue rather than full meta because the current TCG list removes Apollousa and limits several of the best generic tools.
Recovery: Good. Thunder Dragon Fusion recycles banished and GY Thunder monsters and searches follow-up, while Dragondark, Dragonroar, Dragonhawk, and Dragonmatrix keep generating value when discarded or banished.
Going first/second: Flexible, with a slight going-first lean. Going first, aim for Colossus or Titan plus hand traps or a link body. Going second, Denko Sekka, Dark Ruler No More, Nibiru, Evenly Matched, Cosmic Cyclone, Feather Duster, Gameciel, and Pankratops help break boards before the Thunder Dragon engine pushes damage.
Choke points: Stop Aloof Lupine, Batteryman Solar, Gold Sarcophagus, or Thunder Dragon Fusion before the banish chain snowballs. Removing Titan before Thunder effects are available also lowers the deck's interaction ceiling. Droll can slow the search chains, and banish disruption can strand the Fusion follow-up.
Key cards: Thunder Dragon Titan, Thunder Dragon Colossus, Thunder Dragondark, Thunder Dragonroar, Thunder Dragonhawk, Batteryman Solar, Aloof Lupine, Chaos Dragon Levianeer, Black Dragon Collapserpent, White Dragon Wyverburster, Allure of Darkness, Gold Sarcophagus, Thunder Dragon Fusion, Instant Fusion, Millennium-Eyes Restrict.
Key combos: Lupine banishes a Thunder Dragon monster to trigger Dragondark, Roar, or Hawk while setting up Colossus or Titan. Solar sends a Thunder to GY and makes tokens when Thunder effects activate, enabling link climbs. Gold Sarcophagus banishes Dragondark or Roar as a one-card starter. Instant Fusion makes Millennium-Eyes Restrict to insulate a key push. Thunder Dragon Fusion shuffles banished or GY materials into Titan, then searches follow-up for the next turn. Collapserpent and Wyverburster turn LIGHT/DARK bodies into extra link material while keeping cards moving.
