This works because of the way the spell resolves
There are plenty of Boros decks thatll love this like Velomachus Lorehold, or Firesong and Sunspeaker and more still in the Rakdos sphere
The same is true for doubling the number of counters on a player
Roxanne is a neat tool that amps up your treasures and other artifact tokens as well as making little super treasures a bunch
Torens Go Wide Humans Torens, Fist of the Angels is my boyfriend's favorite Commander deck: while at it's core Torens is just a Creatures Matter commander, the fact that these tokens are Humans makes him a perfect commander to lead a Go Wide Humans deck, with some +1/+1 Counter subtheme for added spice
2/1 Now this is the good stuff: cast artifacts, make artifacts, rinse, repeat
