By the time Mishra was defeated, no mage was foolish enough to rely heavily on walls.

Battering Ram

At the beginning of combat on your turn, this creature gains banding until end of combat. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's blocking.)
Whenever this creature becomes blocked by a Wall, destroy that Wall at end of combat.

Fifth Edition

Banding when attacking
If Battering Ram is blocked by any Wall, destroy that Wall at end of combat.

A maximum of one nonbanding creature can join an attacking band no matter how many creatures with banding are in it.

Creatures in the same band must all attack the same player or planeswalker.

If a creature with banding attacks, it can team up with any number of other attacking creatures with banding (and up to one nonbanding creature) and attack as a unit called a "band." The band can be blocked by any creature that could block a single creature in the band. Blocking any creature in a band blocks the entire band. If a creature with banding is blocked, the attacking player chooses how the blockers' damage is assigned.

If a creature in combat has banding, its controller assigns damage for creatures blocking or blocked by it.
