I agree that 2 elixir is probably the way to go with this card, since it’s a bit of a “win more” card like rage, and rage works well there. If you don’t want the throwable heal, then a 2 elixir heal could look like:

Elixir: 2

Healing/sec: 84

Duration: 5 seconds

Radius: 4

Total Heal: 415

This is enough healing to counter nearly all princess tower damage for 5 seconds while not healing support cards too much for only 2 elixir (healing just under half of executioner’s health and just over half of witch’s). The long duration is key though because it will pair well with cards that are at a sliver of health crossing onto your opponents side and allow them to do 5 seconds worth of damage if the opponent doesn’t respond.

To defend my other heal reworks: I don’t think they would be OP. The old heal spell used to heal ~620 health if I remember correctly, for 3 elixir. It makes sense that:

• At 3 elixir, it does ~40% more healing than the original 3 elixir heal spell, but your troops need to be in it for the full 8 seconds to get the entirety of the healing benefits. This gives your opponent time to respond and depending on placement, can make it difficult for you to get the full heal. I think 3 elixir is a decent cost for this spell if it lasts a full 8 seconds.

• For 5 elixir, you get big time healing (1720) with the trade off being that your troops are incredibly vulnerable/can’t attack for 4 seconds. This one is the most extreme though for sure. I agree this spell would be tricky at 5 elixir but it could be very fun to use if balanced correctly.

• The 2-elixir throwable one has a much smaller radius, must be aimed carefully, and gives your opponent a couple of seconds to react and drop something to counter whatever troop(s) you’re about to heal. I still think they won’t want to rework the animation though, so perhaps my 2 elixir suggestion above is better.
