I have an idea about an archetype with the name "Blood King" composed of Reptile monsters (mostly snakes), with Level changing effect that help on Dark Synchro Summoning. But I know don't know how to contructed or organize it to make it functional, any suggestions would be helpful. Thanks in advance.
Well, I have some ideas here, so take which one you prefe the most:
I would like to see some originally low-Level Dark Tuners that can change their Levels radically, with the non-Dark Tuner Main Deckers making the searching and getting the Dark Tuners on the field easier.
Graveyard effects to aid with perhaps the best Reptile support right now, "Snake Rain".
LP-relating effects, like draining your opponent's LP piece by piece and regaining that much of them, since they are "Blood King" archetype (which kinda remind me of Vampires).
Harming your opponent's monsters' ATK, much like "Venom" monsters do (funnily, Yuri doesn't use Venoms, even if his Dragon is one).
Generic Reptile support, because, let's face it, Reptiles is one of the worst supported Types here and as said earlier, the best support is a mill 4 Spell with a discard cost.
