Ramses, bane of barricades

When Ramses enters the battlefield, destroy all walls. Ramses attacks on each players combat step, ignore effects and abilities that would prevent this. When a juggernaut is blocked by a creature with defender, it gets +2/+0 and trample until end of turn, if the blocker doss not have defender the juggernaut gets +0/+2 and first strike until end of turn instead. Vigilance.
