Infinite Guideline Station + Time Sieve + Eldrazi Displacer

Infinite Guideline Station

Time Sieve

Eldrazi Displacer

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. Move to your next turn.
6. Activate Eldrazi Displacer by paying 2C, blinking Infinite Guideline Station.
7. Repeat from step 2 each turn.

This loop sets up an infinite engine by leveraging Infinite Guideline Station's entrance trigger to flood the board with Robot tokens based on your multicolored permanents. Once transformed into a creature via its station ability, those generated tokens serve as the necessary sacrifice fodder to fuel Time Sieve for endless extra turns. Meanwhile, Eldrazi Displacer acts as the mechanical engine, using its blink ability to continuously reset Infinite Guideline Station so it can flood the board with fresh tokens every single turn.
