You can always leave this as the absolute last resort, next-turn-win-or-lose card. If you had enough healing to survive the next turn, then you could have healed instead of play this card (e.g. if you had miracle, you could have played the miracle first, then leave this until later, when you have no other options).
The only exception would be if you just happened to draw into miracle/anti-death card(s) after getting the extra turn. If you feel this would happen often, then a long term consequence may have some effect. Given the quanta costs and/or card combos as well as the luck required to result in such a situation, I think it's more likely that adding a long term consequence would be pointless since it will very rarely do anything in actual gameplay.
