Hoard Robber + Time Sieve + Academy Manufactor + Pirated Copy

Hoard Robber

Time Sieve

Academy Manufactor

Pirated Copy

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 turning Hoard Robber into a veritable factory with the replacement effects of Academy Manufactor, every successful combat damage step yields a massive surplus of artifacts rather than just a single token. Pirated Copy can even join in by copying the robber to double the incoming loot if needed, ensuring your board is overflowing with the necessary fuel. You then feed five of those generated trinkets into Time Sieve, sacrificing them to immediately steal another turn and keep the lock firmly in place.
