Malcolm triggers, creating a Treasure for each opponent dealt damage this way.
Repeat.
Notes
Once you have one opponent remaining, the loop fails to create enough Treasures to sustain itself. You may use other artifacts as desired or wait another turn until your artifacts are untapped. If you have more than two opponents, this combo will net Treasure(s) per loop, and those can also be used once you only have one opponent remaining.
Results
Near-infinite damage.
Near-infinite tapped Treasure tokens.
