Hoard Robber + Time Sieve + Academy Manufactor + Spark Double

Hoard Robber

Time Sieve

Academy Manufactor

Spark Double

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 loop revolves around Hoard Robber and its clone, Spark Double, which multiplies the damage trigger into a massive influx of tokens thanks to Academy Manufactor's replacement effect. Whenever your attackers connect, Academy Manufactor turns what would be standard Treasures into a bounty of three Treasures, three Foods, and three Clues—easily eclipsing the five artifacts required by Time Sieve. By feeding those newly generated tokens into Time Sieve on each combat step, you can chain extra turns indefinitely and lock your opponents out of the game entirely.
