Yeah. The Deck I want to be able to play is a Shooting Star Dragon Deck to rival my brother's version of a Red Nova Dragon Deck. He actually used an impressive combination of Laval and Flamvell monsters in a way that was entirely unpredictable and lethal in summoning Red Nova (or sometimes not), as he could easily Summon monsters with high ATK and gain a direct attack at his opponent's LP. He also had ways to stop deadly traps like Mirror Force. It was lethal, but at least that Deck didn't negate the effects of a lot of my cards like his current Gravekeeper's one. (Stardust Dragon, Junk Synchron, Quillbolt Hedgehog, Shield Warrior, Herald of Pure Light, Call of the Haunted, Premature Burial, Decoy Dragon, Stardust Phantom, and sometimes Hieratic Dragon of Nuit)

I know that the typical solution would be MST, but when the limit on any card is 3 and he has 3 Necrovalleys, 2 Terraformings and a Field Barrier... I don't see that coming out in my favor. Any advice?

(The reason for Premature Burial is that my siblings and I have an agreement that we can each use one copy of one forbidden card apiece while Dueling each other)
