So La Capitan loves Imbued Vitality: it allows her to hit with Maria Helena's Revenge when her ongoings (or Imbued Vitality itself) is destroyed, and it allows her to destroy and store Ongoings and Equipments with damage. However, I wonder if it comes with a drawback: do the cards under La Capitan gain health? I've never been quite sure on how La Capitan's stored cards, and I thought this was enough of an edge case to ask about.
I'm not so sure that Maria Helena's Revenge will trigger just because her ongoings are no longer a target. As the requirement is for them to destroyed, while the target has simply left play.
I think generally when a card is put under another card it no longer has text, it's supposed to be essentially a blank card. If they still have HP than Final Breath and Battle Forged could be stuck hitting and destroying the same Bee Bot for all eternity.
Whenever I put cards under another card such as La Capitan or Haka's Savage Mana, I put them face down to show they no longer have text. They are still considered Hero, Villain, or Environment cards though and as such will trigger things like Haka's Dominion and Bunker's Ammo Drop.
