How to play Sentry Mode

  • Play it early so you start collecting Sweeping Gazes. The card is a long-fight engine, not a burst tool.
  • Use the generated attacks to trigger on-attack effects. They are free cards, so they fit naturally into decks that reward playing many cards.
  • Upgrade it when the deck is stable. Two energy to one makes it much easier to fit into a turn.

Common mistakes

  • Expecting immediate damage. Sentry Mode needs several turns to pay for itself.
  • Playing it when your hand is already full. The generated card can be wasted.
