Obeka, Splitter of Seconds + Mechanized Production

Prerequisites

Obeka's power is greater than or equal to 8 minus the number of artifacts you control that share a name with the artifact that has Mechanized Production attached. An opponent cannot block Obeka.

Steps

1. Deal combat damage using Obeka, triggering Obeka, causing you to get that many upkeep steps after this phase.
2. Move to your next upkeep step. At the beginning of that step, Mechanized Production triggers, causing you to create a token copy of the artifact it's attached to, and win the game if you control eight or more artifacts that share a name.
3. Repeat step 2 as necessary for the remaining upkeep steps until you win the game.
