Hoard Robber + Time Sieve + Academy Manufactor + Hulking Metamorph

Hoard Robber

Time Sieve

Academy Manufactor

Hulking Metamorph

How it works

1. Attack with Hoard Robber.
2. Hoard Robber triggers on combat damage to a player, creating three Treasure tokens, three Food tokens, and three Clue tokens.
3. Activate Time Sieve's ability by tapping Time Sieve and sacrificing five artifacts you control, taking an extra turn after this one.
4. Repeat.

By casting Hulking Metamorph as a copy of Academy Manufactor, you establish a multiplier that turns any single token creation into a massive windfall of nine total artifacts when Hoard Robber connects with an opponent's face. Every successful combat damage trigger from Hoard Robber replaces its standard Treasure generation with three Treasures, three Foods, and three Clues, easily surpassing the five-artifact sacrifice requirement demanded by Time Sieve. By feeding those newly minted tokens into Time Sieve on each subsequent extra turn, you loop the process indefinitely to secure a definitive win.
