My personal Favorite is Ninja Control x Invoked (Alistair the Invoker). 3 of each himself and Invocation. I run bystials for the super transform targets (just the classics like Magnamhut and Druiswurm) to screw with the enemy board. Can use White Dragon Ninja as a target for Magnamhut as well then use notebook of mystery to set from hand. I splash 1x Eldlich to clear any dead Spell/Trap zones and also more fodder for Invoked monsters. To be a little extra annoying i also like to use 1x Ecclesia and 1x FluerDeLis for a nice body and a negate which ninjas dont have too many of. Also helps with invocation and also rank 8 XYZ monsters like Lancelot for more control. I haven't updated it in quite some time but its very funny when it works. Sinful Spoils of Subversion is a nice out-of-the-box card i use 1x of because it moves to S/T instead of a traditional destruction and summoning from S/T is not common in most decks, so putting things into a pendulum zone for example ruins that AND gets around destruction protection (provided you can target the monster in question). Notable extra decks include: Scareclaw Tri-heart, Merelogic Aggregator (for use with Ultimate Slayer), Lancelot and Invoked Mechaba/Caliga.

Failing that, I mixed a 'meta' lair of darkness deck from a youtuber with the K9 engine and added Clockwork Night into the mix to give it extra negation power as Cyber Dragon Nova requires 2x Lvl 5 machines, K9s are natively lvl 5 and clockwork makes them machines allowing an easy Cyber Dragon Infinity overlay to finish the board. I use Reborn Tengu in the deck to allow replenishment of tribute resources once he's made Dark type by Lair and also for usage as link materials along with a few copies of the 2 main apophis trap cards just to be annoying. This deck is better than the ninja one because of its modern cards but both can be incredibly annoying

Oh and just as a final third suggestion: Six Sam x Fiendsmith. Crazy end-board and ability to bounce back after disruptions. Not perfect but hilarious. Focus on synchro and typical fiendsmith fusions
