I thought about a change of the card and want to have some opinions to this:
* decreasing the ability cost to 1 
* increasing the number of removed effects to 3/4
* removing the multiple using per turn
The only negative effects in the game are:
-Poison
-Freeze
-'Stasis' (Time bubble/delay)
-Gravity Pull
I highly doubt that any creature will really be affected by more than 2 debuffs (seeing that very few of them have any synergy with each other, minus Freeze/Poison, which is usually found only from duo-

/

decks), so increasing the number of removed effects doesn't really help. It'd be
a better change if you increase the amount of HP healed from 3 up to something else. Otherwise, the other two changes (efficient cost and removal of multiple uses) sound okay, and may make it a little bit stronger, but not overpowered (the upkeep is what bring it down heavily).
