GLC Deck - Black Widow

This Grass GLC “Black Widow” deck is built around stacking Retreat Costs to amplify the damage output of Tangrowth (UNM 10) and Ariados (EVS 6), both of which scale damage based on the opponent’s Retreat Cost. Stadiums like Galar Mine and Team Aqua’s Secret Base, plus Tools like Gravity Gemstone, combine with Ariados’s Big Net Ability to consistently raise Retreat Costs and punish the opponent’s mobility. The search chain of Grotle (SHF 8) → Sawsbuck (EVS 11) → Turffield Stadium → Roserade (EVS 2) creates a resilient consistency engine, ensuring access to Grass Pokémon, Energy, and utility cards. Budew (DCR 45) provides early-game disruption with Item lock, while Gossifleur (EVS 16) and Tangela (HS 80) give strong opening options for board setup or early poison pressure. In the mid-to-late game, Tangrowth serves as the heavy hitter with 140 HP bulk, while Ariados doubles as both support and secondary attacker. The deck’s strategy is a balance of consistency, disruption, and scaling damage—using synergy between Retreat Cost manipulation and efficient search engines to lock down the opponent while steadily ramping into powerful knockouts.
