By fueling Super-Skrull's blue activation to force an opponent into drawing four cards, you directly feed the passive tax engine of Smothering Tithe. Because Mondrak, Glory Dominus is doubling every single token created, those missed tax payments yield an abundance of Treasure tokens rather than just a few. You then sacrifice just six of those newly minted Treasures to pay for the next activation, leaving a massive surplus of mana and tokens to spare.
