Expertise

Expertise is an uncommon Silent skill that draws cards until you have 6 in hand for 1 Energy. In practical terms, if you have 3 cards in hand, it draws 3; if you have 5, it draws 1. The effect scales inversely with current hand size, making it most powerful when your hand is lean. A near-empty hand with Expertise fills back up to 6 cards — exceptional draw density when conditions align.

Expertise is best in decks that spend their hand aggressively each turn, ensuring a low card count before playing it. It pairs naturally with aggressive card-playing strategies or builds that use zero-cost cards to dump the hand before refilling. In decks that intentionally hold large hands, Expertise can whiff and draw very few cards. Upgraded, it draws until you have 7 in hand, which provides one additional card at every hand size.
