Infinite Guideline Station + Time Sieve + Airbender Ascension

Infinite Guideline Station

Time Sieve

Airbender Ascension

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, Airbender Ascension 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 fascinating loop relies on Infinite Guideline Station as both your token engine and your eventual flying beatdown threat, leveraging its entry ability to flood the board with Robot artifact creature tokens based on your multicolored permanents. To fuel Time Sieve, you tap creatures to turn Infinite Guideline Station into an artifact creature via its station ability, giving you the exact fodder needed to sacrifice five artifacts for endless extra turns. Meanwhile, Airbender Ascension accumulates quest counters each time a creature enters and neatly resets Infinite Guideline Station at your end step so you can continuously retrigger its token-generation upon reentry.
