Infinite Guideline Station + Time Sieve + The Mind Stone

Infinite Guideline Station

Time Sieve

The Mind Stone

How it works

1. Cast Infinite Guideline Station either from your hand or from the command zone by paying plus commander tax if applicable.
2. When Infinite Guideline Station enters, it triggers, creating a 2/2 Robot artifact creature token for each multicolored permanent you control.
3. Activate Infinite Guideline Station's station ability by tapping any number of creatures with total power 12 or greater, putting at least twelve charge counters on Infinite Guideline Station, causing it to become a creature.
4. Activate Time Sieve by tapping it and sacrificing five Robots, causing you to take an extra turn after this one.
5. At the beginning of your end step, The Mind Stone triggers, blinking Infinite Guideline Station.
6. When Infinite Guideline Station enters, it triggers, creating a 2/2 Robot artifact creature token for each multicolored permanent you control.
7. Repeat from step 3 each turn.

This ingenious engine centers around Infinite Guideline Station, which floods your board with Robot artifact creature tokens the moment it enters the battlefield. You use those very tokens to power up the Station's crew ability—turning it into an artifact creature—while simultaneously feeding sacrifices into Time Sieve to harvest an endless stream of extra turns. To keep the loop going indefinitely, The Mind Stone's harnessed end-step ability blinks the Station away and brings it right back fresh, resetting its enter-the-battlefield trigger to churn out a brand new batch of Robots every single rotation.
