A simple Rokket deck with cheap, readily available cards, focused mainly on summoning Beelze of the Diabolic Dragons and using its destruction immunity to your advantage with your other big boss monsters.
Scarlight Red Dragon Archfiend can destroy all other Special Summoned monsters on the field, and deal 500 damage to your opponent for each destroyed monster. Obviously Beelze is immune to this, so you get another 3K attacker to follow up on the nuke.
Borreload Furious Dragon can target 1 monster your control and 1 card the opponent controls to destroy them. If you target Beelze with this, it'll still pop your opponent's card, so you get free quick-effect removal every turn.
Topologic Bomber Dragon destroys all monsters in the Main Monster Zones if a monster is special summoned to a zone a Link Monster points to, so just summon Beelze in one of the 3 zones below it.
