4. Resolve both Time Stretches, causing you to get four extra turns after this one.
5. Move to your first extra turn.
6. Activate Conduit of Worlds by tapping it, targeting The Mirari Conjecture and causing you to pay 4 to cast it from your graveyard.
7. The Mirari Conjecture enters with a lore counter on it, triggering its first chapter ability, returning an instant card from your graveyard to your hand.
8. Move to your second extra turn. At the beginning of your precombat main phase. The Mirari Conjecture triggers, putting a lore counter on it. Its second chapter ability then triggers, returning Time Stretch from your graveyard to your hand.
9. Move to your third extra turn and repeat from step 1.
