Ok, if you're gonna use Quillbolt Hedgehog, at least go for the Quillbolt loop with Imperial Iron Wall and Mass Driver. Basis is to summon a tuner with Quillbolt in the grave, then use Mass Driver on it. With Imperial Iron Wall on the field he'll be sent to grave rather than being removed from play, so you can special summon him again and again to OTK your opponent via Burn.
Double Summon is a -1 with almost 0 redeeming value. Get rid of it. United We Stand is bad, like almost all Equip Spell cards. No reason to run Sakuretsu Armor when you're already running 2 D Prison. Instead, you need chainable traps to avoid getting OTK'd when your opponent blows up the field. Therefore, you need Roars or Wabokus. You can also still use a copy a Solemn. Trap Dustshoot is another good way to prevent OTK's. In general, BTH is better than Saku/D Prison since it can stop cards like Breaker and DAD while D Prison/Saku can't.
Lastly, Brionac is limited. You don't need 2x Thought Ruler. Add in Red Dragon Archfiend. You don't need 2x Gaia Knight (don't even need 1 since you already have Brionac and Goyo). Add in Magical Android to have a different level 5 Synchro.
