Hoard Robber + Time Sieve + Academy Manufactor + Synth Infiltrator

Hoard Robber

Time Sieve

Academy Manufactor

Synth Infiltrator

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 loops infinite turns by turning a single successful attack into a mountain of sacrifice fodder. When Hoard Robber deals combat damage to a player, Academy Manufactor steps in to multiply that single Treasure into a massive trio of Treasures, Foods, and Clues. You only need five of those newly minted artifacts to feed Time Sieve's activation cost for an extra turn. Meanwhile, Synth Infiltrator ensures you have a backup copy of Hoard Robber ready to multiply the carnage even further once it enters as a copy of the rogue.
