Something went wrong when you picked cursed key card, it always decrease 1 base energy at start of combat, you can add 1 energy back once you played that card.
(also apply to other relic that offer base energy I guess)
Seems you didn't play cursed key card in act 3, so you lose energy every combat.

good to know... is this intended mechanic ? my deck was like 50 cards at that point so it would be hard to get it to play it

Absolutely not intended, sorry about that. There's a technical update coming soon-ish that changes the way carded relics are saved, which fingers crossed will stop this from happening.
