Rustcursed Armor

Equipped creature gets +1/+3 and has:
"Whenever this creature deals combat damage
to a creature, destroy target equipment attached
to that creature."
Equip {2}
Not only does this heavy suit of rust-thick armour
deflect blows but the ruin-hexes scored into its plates
spread tendrils of oxidising entropy across the
attacker's treasured artefacts.
