Reflex

SilentSkillUncommon
Sly.
Draw 2 cards.

Sly, draw 2 (3 upgraded). Sly means that if the card is discarded from your hand during your turn, it is played for free at that moment. Paying its printed 3 Energy for a draw 2 is almost never the plan; you want a Dagger Throw, Prepared or Survivor to toss it and get the draw for nothing. The discard at the end of your turn does not count.

When to take Reflex

Only for a Silent with three or more discard outlets, where it becomes a free draw 2 almost every time a discard comes up. Without them it is just a 3-cost draw 2 sitting dead in hand.
