Quick Answer

Treat Gwent as a route, not a random side activity. Buy cards from innkeepers and merchants as soon as you meet them, play named opponents before story locks, and make manual saves before tournaments or major quest branches.

Collection Routine

WhenActionWhy
New settlementCheck innkeeper and merchant inventoryMany cards are easy to miss by ignoring shops
New named NPCPlay if the dialogue option existsSome opponents are tied to quest availability
Before story escalationMake a manual saveProtects tournament and quest-card outcomes
After winningUpdate your deck immediatelyKeeps the next match easier

No-Spoiler Priorities

  • White Orchard: learn the basics and buy what is available.
  • Velen and Novigrad: keep merchant checks routine.
  • Tournament-style quests: save before starting and finish the chain deliberately.
  • Skellige: do a regional sweep instead of leaving island opponents for the end.
