Reinforcement of the Army is staple here. You have three targets and both Prisma will be constantly returning to the deck via fusion and Test Tiger effect, other than looks good.

Sparticus and Alexander are crap cards for GB. Don't bother using them. You want to focus on Gyzarus and Heraklinos instead. They are much better and more rewarding goals. If you're going to run Rescue Cat, you should run a copy of Airbellum to give yourself access to Synchros. Double Tag Team is a crap card that you won't be able to make use of often enough and is too slow for GB. War Chariot needs to be maxed at 3 since you will absolutely pwn using it in combination with Equeste, but you need to get it in your hand as early as possible. It destroys so many decks.

If you listen to neko's suggest you will be able to abuse War Chariot using Esquente, if you should do that I would also recommend a single copy Respite, it really worked for me as it was able to return excess cards in hand such as War Chariot (when you have two or more).

If i put one colosseum in my deck and one disarm woud it help?

No they won't.

and no one mentioned this eh? 2 darius is no good, i know darius may be BTH'd..etc but i find 2 is dead in my opinon 1 dariu was always good so i would swap it for a E-call to get Prisma, but since you have stratos then add an X-saber airbellum instead.
