Without further ado, let's look at some of the more important cards for this deck's victory strategy. You can find the deck list for the deck we are to go over on TappedOut by clicking here. As you can see from the keyword soup, above, there are a ton of ways to make Prosper make you, well, prosper. These means include 'impulsive' draw, spells that steal from opponents' resources, and spells with suspend, rebound, madness, adventure, cascade, and foretell.
As a result of this realization, this deck is effectively a spellslinger deck that works through exiling cards through various means to cast later on. This does not solely apply to the cards you exile with Prosper, however. Furthermore, whenever you play a land from exile or cast a spell from exile, you create a single-use, mana-producing Treasure token.
The way that Prosper works is that at the end of each of your turns, you exile the top card of your library, which you can then cast until the end of your next turn.
