Real mathmatic application will show the amount of deck thinning this guy provides nets you more effort required than average measurable reward per game.

The worst part is its not even good. Could be a 0/1 for 7cmc and nobody would care, its overall functionality would be uneffected - you want the cycle, and maybe to cheat it out later by reanimation, if at all. A 3/4 swampwalk for 5? Eww.

Given the average number of cards you need to thin per turn to make a relevant, significant, and consistent difference - much less one that can be legitimately considered advantageous - Cards like this that function soley for the purpose of lowering virtual deck count end up making the deck worse off than a card that provides real advantage or strategic value
