Here's the list of all my max myths and divines I have never used:
2 HPVs, 3 Rusty Energy Armors, Archimonde, 2 Sparked Runners, 4 Rolling Beasts
Abomination (D), Damaged Armor Annihilator, Scrapped Energy Blaster, 2 UPCs, Distance Controller, Bunker Shell, 2 Bulldogs, Stormweaver
Cockpit Electrocuter, 2 Cockpit Piercers, Flaming Scope, Desert Snake, Desert Fury
2 Unreliable Guardians, Backstabbing Guardian, Rail Gun, Flaming Spear, Anguish, Murmur, Swoop, Greedy
I have quite a few more max myths/divines I no longer use, but that's not really relevant.
