I'm not convinced it's worth the word count, although it's worth bearing in mind. However, I think (and more playtesting is needed) that it may be too weak at 1 life per counter. I think it's unlikely to get you more than 3, or maybe 4, in a normal game.
I think I'd expect either

for Chargecast Cancel, or 

for Chargecast Cancel+Trickbind.
Playtest indicated this was a bit weak at 3
; would 2
be too strong with abilities in there as well as spells?
Changed to activated abils and added reminder text.
