Marvin, Murderous Mimic + Synthesizer Labship + Lost Jitte

Marvin, Murderous Mimic

Synthesizer Labship

Lost Jitte

How it works

1. Animate the land, if needed.
2. At the beginning of your combat phase, Synthesizer Labship triggers, animating Lost Jitte.
3. Activate Marvin using Synthesizer Labship's station ability by tapping the animated land, putting a number of charge counters on Marvin equal to the animated land's power.
4. Activate Marvin using Lost Jitte's ability by removing a charge counter from it, untapping the animated land.
5. Repeat from step 3.

This clever loop turns the unassuming Marvin, Murderous Mimic into an engine of limitless mana by letting him borrow the activated abilities of his fellow artifacts. Thanks to Synthesizer Labship's combat trigger, Lost Jitte becomes an artifact creature for the turn, allowing Marvin to inherit both the station ability and the Jitte's charge-counter manipulation. Once the land is animated by other means to provide the initial power, Marvin uses the station ability—fueled by tapping that land—to load up on charge counters, which he can then spend on Lost Jitte's ability to untap the very same land. By cycling back and forth between tapping the land for mana and untapping it with Marvin's borrowed Jitte effect, you generate infinite untaps and infinite mana from your lands.
