Tanglewalker

This creature has banding as long as you control a Plains. (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 blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)

Whenever this creature attacks and isn't blocked, you may destroy target artifact defending player controls. If you do, this creature assigns no combat damage this turn.

Each creature you control can't be blocked by more than one creature.

This creature can't attack unless defending player controls a Forest.

When you control no Forests, sacrifice this creature.

Flying

This creature can't attack unless defending player controls a creature with flying.

: Target creature you control can't be blocked by creatures with power 2 or less this turn.
