One of the funniest, most inventive things I've ever seen run with a Berzerker's Glaive -
Lord: Glaive; Terminator Armour; Chainfist; Feel No Pain; Daemonic Strength; Collar of Khorne; Furious Charge. The player also ran a Daemonic Rune, but I would've probably left it at home.
The player Deep Struck the Lord near a Teleport Homer that was near a unit closing in on a Land Raider. The opponent asked why he showed up over there, and the reply was,
"I didn't want to risk losing him to a bad scatter, so I went with the Teleport Homer."
The opponent felt that a Strength 6 had absolutely no chance of harming that Land Raider, so ignored the Glaived Lord. Next turn, the Land Raider took nine Strength 10 + 2d6 Penetration attacks. It did not survive.
