Chaos Thunder Dragon

Tries to make Thunder Dragon Colossus, along with a rank 8, and maybe Seals.

Possible Giantrainer package (or maybe just giantrainer on its own): 1x Coach King Giantrainer, +1x King's Sarcophagus, 1x Duamutef Blessing of Horus

There might be room for some consistency tools like Starleige Seyfert and Omni-Dragon Brotaur.  Also considering adding Blazing Cartesia to have another way to make LAD and be able to make Bystial Dis Pater, plus maybe another tuner like Mental Tuner.

Recently cut Zeus and Chaos Angel to make room in the extra for new galaxy stuff, and moved up to 60 cards.  Also cut Shadow's Light and the bystial targer for it (seleglare) for blue-eyes and the field spell.  Thinking about Spright Sprind right now, one of the only extra deck thunder monsters I can make that can go into colossus, or maybe even something like the thunder nemeses monster.
