Another way to think of this is, "Do we want the flicker cards to enhance your cards or hurt your opponents' cards?" You tend to flicker things of yours that you want to come back into play, such as cards with "enter the battlefield" (ETB) effects, while you tend to flicker things of your opponents they don't want to have leave and come back, such as creatures with +1/+1 counters and Auras
Its a nasty habit, but theres finally a glimmer of good in it
Of course, thatd be true of Kroxa, too, so what are we even talking about here
Of course, in terms of stats there are a few more powerful options these days, but in terms of filling out the curve and offering some externalities, Blade Splicer continues to be among the first white three-mana cards that I consider for Cube inclusion
For Cubes, which are designer formats with unique metagames and a lack of reliable statistics, defining power level is nontrivial
