This is a classic Control list for Standard Pauper, playing lots of permission spells and card draw and then winning off the back of a particular potent late game creature - in this case, the surprisingly effective Whirlwind Adept. The list is also optimized to power out Treasure Cruise as quickly as possible, utilizing the 'cantrip' creatures, lots of spells, and even Evolving Wilds to get a bunch of cards into the graveyard as quickly as possible. Other than the hard counters, the deck also dedicates several slots to bouncing an opponent's creatures with Griptide and the like, giving it the time it needs to eke out some major card advantage and transform that into a win.
