mtg progenitus commander deck Pro 100+ Box on strip Magic: The Gathering - Progenitus

Talk about an absolutely perfect card for that SunforgerSunforger build we were talking about earlier

You can also abuse infinite combos, which makes The Gitrog Monster a viable combo deck in cEDH

This card is very good in faeries deck, considering that its a faerie and that you can cast two spells on your opponents turn, which is good for cards like Alela, Cunning Conqueror and Voracious Tome-Skimmer

Its also an artifact, so you have additional synergies with affinity, metalcraft, and so on

If an effect instructs you to choose a card name, you may choose one of those names, but not all of them (though you might want to write it down and not just say it out loud)

I especially like how much control you have over when this transforms because it only triggers off spells that cost 4 or more, or you can put counters on the Emperor so you just need to trigger it once or twice to flip
