This deck easily defeats decks like sky striker and altergeist who search or use a lot of spell/trap cards.
Tip:
Use Eradicator epidemic virus on Colossus
You can also run a danger! engine. But it's no fun :) If you want to me post a Danger! thunder dragon decks tell it in the comments.
There are 2 main combos:
1. Aloof lupine + Anything
Normal summon Aloof lupine and banish something from your hand to Thunder Dragonroar from your deck and with its effect special summon Thunder Dragondark then use Aloof lupine and Thunder Dragondark to link summon LANphorhynchus then add Thunder Dragonhawk and activate its effect and summon any thunder dragon. Use the thunder dragon you summoned for Thunder Dragon Colossus.
2. Batteryman Solar + Thunder Dragonhawk
Normal summon Batteryman Solar and send Thunder Dragonroar to the graveyard then activate Thunder Dragonhawk effect to summon Thunder Dragonroar (You get 1 token because of Batteryman solar effect). Use Batteryman Solar and the token to link summon Some summer summoner than use Thunder Dragonroar to summon Thunder dragon Colossus than special summon Thunder Dragondark by the effect of Thunder Dragonroar. Use Some summer summoner and Thunder Dragondark to link summon decode talker and add Thunder dragon fusion with Thunder Dragondark effect. Activate Thuder Dragon fusion and shuffle Thunder dragonroar, Thunder dragonhawk, Thunder dragondark to the deck and summon Thunder Dragon Titan.
