Infinite Guideline Station + Time Sieve + Lilysplash Mentor

Infinite Guideline Station

Time Sieve

Lilysplash Mentor

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 Lilysplash Mentor by paying 1, blinking Infinite Guideline Station.
7. Repeat from step 2 each turn.

By unleashing Infinite Guideline Station, you instantly flood the board with a squad of 2/2 Robot artifact creature tokens scaled by your multicolored permanents, providing the exact fodder you need. You then harness that raw material to fuel Time Sieve, sacrificing five of those artifacts to cleanly chain infinite turns. To keep the engine running indefinitely, Lilysplash Mentor steps in to repeatedly blink your now-creature Infinite Guideline Station during each bonus turn, resetting its entrance trigger to generate a fresh batch of Robots and repeat the entire loop.
