Improvement
Buff
At the end of combat, Upgrade a random card.
This only exists on the Power version of Mad Science, the custom card built at the Tinker Time event in Glory, when Improvement was the rider you chose. Playing the card grants 1 stack. When the combat ends, for each stack the game picks a random upgradable card from your deck and upgrades it permanently. It never decays and stacks with repeated plays in one fight.

Notes
Cards already at their maximum upgrade are excluded, and each stack picks a different card, so 2 stacks mean 2 upgrades. The choice uses the combat card-selection RNG and cannot be steered. It is a Power, so it must be played every combat to fire; an upgraded Mad Science is Innate, which makes that easy. Nothing else in the game applies this power.
