For a while a blue version of this deck using Stock Up became popular, but red or Rakdos is the more traditional option, with Goblin Engineer and Welder giving the deck more consistency, and Pyroblast becoming a one mana counterspell once Painter's Servant is on the field
The card may not be mechanically powerful, but the Whelan artwork ensures it still holds value today
Since then, prowess has become a rare but highly desirable keyword
It is just a weird discard outlet Trade Route on legs
I'd prefer it just make it, since then they can answer it with bounce, exile, shuffle and answer your winner too in one spell
Generally I view Bargain as more of the combo or big control card with Necro being better for agro or disruption decks
