Hoard Robber + Time Sieve + Academy Manufactor + Sakashima the Impostor

Hoard Robber

Time Sieve

Academy Manufactor

Sakashima the Impostor

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 cunning setup uses Academy Manufactor as an exponential multiplier to turn a single successful strike from Hoard Robber into a mountain of nine total artifacts—three Treasures, three Foods, and three Clues. With Sakashima the Impostor neatly copying Hoard Robber to double your attacking force, or standing ready to bounce back to hand if the board gets hostile, you will easily produce well over the five artifacts needed. You then feed those riches directly to Time Sieve, sacrificing just five of them to chain extra turns indefinitely until your opponents are entirely locked out of the game.
