Infinite Guideline Station + Time Sieve + Meneldor, Swift Savior

Infinite Guideline Station

Time Sieve

Meneldor, Swift Savior

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. Deal combat damage using Meneldor, triggering Meneldor, 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 elegant loop transforms the raw power of Infinite Guideline Station into an endless chain of extra turns by weaponizing its entry trigger. Once the Spacecraft is animated through its station ability, Time Sieve steps in to trade a handful of the Robot tokens for a brand new turn. To keep the engine running, Meneldor, Swift Savior blinks Infinite Guideline Station upon dealing combat damage, wiping away its counters so it can re-enter, flood your board with fresh tokens, and reset the loop all over again.
