Prep Time

ColorlessPowerUncommon
At the start of your turn, gain 4 Vigor.

A 1-Energy Power: at the start of each of your turns you gain 4 Vigor (6 upgraded), beginning with the turn after you play it. Vigor adds itself to your next Attack from a card and applies to every hit of that Attack. Unspent Vigor does not decay, so a turn without an Attack banks it for the next one and the Power adds another 4 on top.

When to take Prep Time

A Colorless Power worth taking when your deck has multi-hit Attacks, where 4 per hit adds up fast. In a single-hit deck it is only a fine 4 damage a turn for 1 Energy.
