Hoard Robber + Time Sieve + Academy Manufactor + Clever Impersonator

Hoard Robber

Time Sieve

Academy Manufactor

Clever Impersonator

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 clever engine spins an infinite sequence of extra turns by turning a single successful strike into an overwhelming pile of resources. When Hoard Robber connects with an opponent, its combat damage trigger normally yields a modest single payment, but Academy Manufactor steps in to completely multiply your yield, forcing the creation of a massive trio of Treasure, Food, and Clue tokens all at once. To ensure you have a second copy of this crucial replacement effect on the board, Clever Impersonator easily enters as a clone of Academy Manufactor to supercharge your token generation even further. Finally, Time Sieve happily gorges on just a fraction of those newly minted artifacts to grant you an extra turn, letting you repeat the whole assault indefinitely.
