This Deathwish Succubus deck uses Archespore, which has historically been neglected in these builds due to brick potential with Brewess: Ritual. Archespore has the best stats out of any 4-prov deathwish bronze and it thins, which really helps this deck draw its key cards. You can try to thin the archespore before consuming Brewess: Ritual, but even if you can't, the chances of bricking Archespores through Brewess: Ritual is quite small if you aggressively mulligan deathwish bronze units.
In r1, your objectives are to thin Archespore, play first form Dagon if you have it, thin with Brewess Ritual, consume the Dagon-infused deathwish units and preferably set up Giant Toad carryover as well as one (best if it's only one) Succubus.
During each mulligan phase, you should try to look ahead and count how many consumes are required to activate all your deathwishes and compare that to how many consumes you have available. Don't forget to count leader charges and Giant Toads in your graveyard. Then mulligan accordingly to bring these two numbers as closer together.
Dettlaff requires 2 consumes. Succubus requires one consume per turn starting from the 5th-to-last turn of the round. Arachas Queen requires a net of 2 consumes if eating Dettlaff and usually 4 consumes if eating Succubus.
