Far below Fatal Push: two mana for -2/-2 is poor, while the -6/-6 mode costs a permanent and needs a shell that profits from sacrifice.

Could be wrong if A proven Modern sacrifice shell with plentiful disposable artifacts or creatures could make the kicked mode a useful removal-plus-outlet package.

Legacy's removal must be much cheaper or more reliable; this is substantially worse than Fatal Push unless sacrificing a permanent is intrinsically profitable.

Could be wrong if Cheap artifacts such as Mishra's Bauble could reduce the practical sacrifice cost in a presently underrepresented shell.

Ichor Wellspring can make the kicker tolerable in Grixis Affinity, but Cast Down is far more reliable and -2/-2 is a weak default mode.

Could be wrong if If artifact-sacrifice synergies prove central, Wellspring-style fodder could make -6/-6 removal more attractive than expected.

A one-shot sacrifice outlet attached to temporary shrink is highly replaceable; optimized decks prefer unconditional removal or repeatable free outlets.

Could be wrong if A commander that rewards both sacrificing artifacts and reducing toughness could turn its otherwise inefficient two effects into one useful card.

Two mana -2/-2 is useful combat removal, and sacrificing a doomed creature can answer nearly anything with -6/-6, though it is often a two-for-one.

Could be wrong if Unknown creature toughness, artifact fodder, and sacrifice payoffs could move it from dependable removal to narrow filler or premium synergy.
