Defense = Ghost Town

[xStrayKnightx]

{Lord of Shatterskull Pass} + {Sword of Kaldra}.

Get the Lord up to level 6. Triggered ability kicks in, dealing 6 damage to each creature defending player controls.

If he's equipped with the Sword, he's no longer a 6/6. He's an 11/11 (the Sword giving him +5/+5), and the triggered ability of "whenever equipped creature deals damage to a creature, remove that creature from the game".

Swing with Lord of Shatterskull Pass equipped with Sword of Kaldra.
Deal 6 damage to each creature defending player controls.
Sword of Kaldra's ability kicks in, exiling all damaged creatures.
Lord of Shatterskull Pass deals 11 damage to opponent.
