When to Pick Dark Shackles
Consider this card when its cost, type, and keywords support what your deck is already doing. It is usually better when it solves a clear problem: damage, block, scaling, card draw, or synergy with your current relics.
When to Skip
Skip it when your deck already has enough cards in this role, when the energy cost does not fit your curve, or when it needs support pieces you do not have yet.
Upgrade Priority
Upgrade priority depends on how much the upgrade changes the card's output. Damage, block, cost reduction, and repeatable scaling upgrades are usually higher priority than small numerical improvements.
Play Tips
Evaluate this card together with your current deck instead of in isolation. The best picks in STS2 are cards that make your next elite, boss, or hallway fight easier right now.
