Dexter Drake Flex Fighter - 2XP Power Word or Dirty Fighting

Very cool and versatile Dexter Drake build. Flex fighter.

With a +5 Intellect, you can both fight and gather clues effectively with your hand and arcane assets.

The engine of this base deck is Molly Maxwell. Once you get her on the board, you can tutor for any card you need. Calling in Favors works incredible for her, both for initially finding her (sacrificing an Arcane Initiate) or healing all of her horror by recalling her to find another Arcane Initiate, which you can exhaust for a free Spell card and immediately discard to play Molly at a reduced cost per Dexter's investigator ability.

Since Dexter's off-class is Rogue, he has plenty of economy to get all of his core cards and reuse Molly as a tutor.

After the first scenario, you would have a total of 6-8 extra XP on top of the scenario rewards (two from Arcane Research, two from Down the Rabbit Hole, two from Charon's Obol, and possibly two from Delve too Deep). Don't forget to tutor for Delve too Deep with keyword Insight! :)

From there, you can branch out to whatever deck build you like. If you want to go all in on Power Word, you can sink XP into it fast. You can then sideboard Words of Power to make sure you're drawing Power Word. You can also go Underworld Market + Dirty Fighting and include any of the Mystic evade cards you like (Mist, Blur, Ineffable). I would prioritize Brand of Cthugha as an upgrade no matter what path you choose. You eventually want to upgrade to Cyclopean Hammer as a boss finisher.

After, you can choose which stat booster you want (Blood Pact vs. Prophetic, or both) and keep tailoring your deck based on your choices.
