This is not really comparable to SoB since it does not have the offensive deckout potential going for it.
It does compare more directly to
based draw mechanics. More specifically, draw based card advantage
While this is typically a jealously guarded core of the
element, I actually think its okay here.
1) It justifies a time maninuplation like effect without actually thematically requiring time manipulation per say (via an adrenaline overload)
2) The draw bonus it provides, while a much stronger burst, is weaker in the long run than under
3) It serves a different niche than most of time's draw based card advantage
-Time provides means of consistent draw based card advantage via hourglass and its nymph
-This card provides distinct burst drawing, with subsequent down time and significant penalty / side effect
-Time's draw capacity can be readily chained
-This card's utility is not amenable to chaining (it would quickly kill you and loses efficiency beyond the first use)
I think this is enough to keep it very distinct both thematically and mechanically.
