There and Back Again + Time Sieve + Hex Parasite

There and Back Again

Time Sieve

Hex Parasite

How it works

1. At the beginning of your precombat main phase, There and Back Again triggers, putting a lore counter on it, triggering its third chapter ability.
2. Holding priority, activate Hex Parasite by paying 1B/P, removing a lore counter from There and Back Again, and giving Hex Parasite +1/+0 until end of turn.
3. Resolve the There and Back Again ability, creating a legendary 6/6 Smaug creature token.
4. If you control two Smaugs, put one into your graveyard due to the legend rule.
5. If a Smaug dies this way, it triggers, creating fourteen Treasure tokens.
6. Activate Time Sieve by tapping it and sacrificing five other artifacts, causing you to take an extra turn after this one.
7. Repeat each turn.
