Decks/Exposing Vulnerabilities

Exposing Vulnerabilities

by aeideIronclad14 cardsMay 1, 2026

This deck is just all about stacking vulnerabilities and exploiting them. Really lean deck, and isn't the best against AOE, but an absolute single-target monster; plus most AOE mobs have less health and die in a couple hits with the vulnerability anyway.

Assessment

Strengths

  • Strong Vulnerable synergy (9 cards)
  • Solid defensive options
  • Has Strength for damage scaling
  • Has energy generation for bigger turns

Weaknesses

  • Dexterity payoffs (2) but no enabler — add a card that produces Dexterity
  • No AoE — may struggle against multiple enemies
