Acrobatics
Acrobatics is a common Silent skill that draws 3 cards and discards 1, costing 1 Energy. It provides exceptional draw at a very low effective cost, since discarding a card is often neutral or beneficial for the Silent — fueling discard synergies with cards like Tactician, Reflex, or Sneaky Strike. Even without those synergies, swapping a weak card for three new ones frequently results in a strong hand.
Acrobatics is a staple in many Silent builds due to its raw draw efficiency. In a discard-synergy deck, it becomes one of the strongest draw cards in the game — drawing 3 and triggering Reflex or Tactician can generate energy and cards simultaneously. Upgraded, the discard is removed entirely, making it a pure draw-3 for 1 Energy with no downside, which is among the best card draw in the game. Nearly always worth considering as an upgrade target.
