Mirran against Phyrexian

What this set is

Mirrodin Besieged is the middle set of the Scars of Mirrodin block and the point where the war is out in the open. Every card carries a Mirran or Phyrexian watermark, and the booster packs themselves came in a Mirran version and a Phyrexian version.

It added two mechanics, one for each side. Battle cry, on Mirran cards, gives each other attacking creature +1/+0 whenever this one attacks. Living weapon, mostly on Phyrexian Equipment, creates a 0/0 black Phyrexian Germ token and attaches the Equipment to it when it enters.

Several of its cards are still played well outside the block. Blightsteel Colossus, Sword of Feast and Famine, Green Sun's Zenith, Consecrated Sphinx, Inkmoth Nexus and Go for the Throat are all from here.

Where You Can Play It

Format legality

Mirrodin Besieged shipped under a single code. It predates Pioneer, so the set is legal in Modern and the eternal formats.

Not Standard-legal. Standard only ever holds the last few years of sets, so everything this old has long since left it. These cards are still playable in Modern, Legacy, Vintage and Commander. Commons from any set are Pauper-legal; that isn't listed per set here.

Limited

The draft format

Drafted as Mirrodin Besieged, Scars of Mirrodin, Scars of Mirrodin. The faction split carried over, and infect got deeper with the new pack.

Phyrexian infect

Poison aggro

Seventeen infect cards in the new pack made poison a real draft plan, especially in green and black.

Mirran battle cry

Go wide

Battle cry pays off for attacking with many creatures, which pairs with the token makers and cheap artifacts the Mirran side already had.
