If your threat outclasses all theirs, this line should be one of your first choices

[15] An English version was released on May 26, 2014, on Weekly Shonen Jump

Supreme King Dragon Darkwurm X DARK Level 4 [ DragonPendulumEffect ] ATK 1800 DEF 1200 P Scale 5 Once per turn, if you control no monsters: You can place 1 "Supreme King Gate" Pendulum Monster from your Deck in your Pendulum Zone, also you cannot Pendulum Summon monsters for the rest of this turn, except DARK monsters

Looking on the type line, we can see that he's a creature, and his specific creature type is "Troll Shaman"

Integrating some form of condition assessment (even a rough one) would improve accuracy.

I think maybe the Mother of Runes are unneeded here, perhaps swapped for Withered Wretch if the mana base can handle it
