Hoard Robber + Time Sieve + Academy Manufactor + Phyrexian Metamorph

Hoard Robber

Time Sieve

Academy Manufactor

Phyrexian 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.

This ingenious setup hinges on the staggering multiplicative power of Academy Manufactor, transforming every single Treasure generated by Hoard Robber into a massive windfall of three Treasures, three Foods, and three Clues all at once. To ensure you have enough fodder to feed Time Sieve every single cycle, Phyrexian Metamorph steps in as a clever tactical clone to duplicate Academy Manufactor—or another critical piece—doubling down on your token production. With nine total artifacts hitting the board from a single successful combat damage trigger, you easily surpass Time Sieve's five-artifact sacrifice requirement to chain infinite extra turns and lock your opponents out of the game entirely.
