mtg commander 2019 decks 2019: "Mystic Intellect" Deck each player chooses a legendary creature as the commander of their deck Magic The Gathering Commander Masters

Also, its one of the few black creatures in this list, and black doesn't get too many copy effects, so this Phyrexian shapeshifter has less competition

The deck wins fast or loses fast

Luckily black has access to a handful of spells that can change a lands type to Swamp

It may not be as efficient as Mutavault in this department, but it gets the job done

Very similar to Phyrexian Arena, here you get your extra card much faster, and its more flexible too

Add in the fact that the card is actually a good legendary Blood Artist that provides card draw and a strong finisher in Sephiroth, One-Winged Angel, and I have to say that this is a 10/10 design and a great commander
