Gangplank: With Muramana, Shiv and IE, has fantastic poke potential. While his ult doesn't do great damage, it covers the width of the lane and provides a reliable slow. His 'E' provides a team-wide buff. He also has sustain with his oranges.
Trundle: While Pillar is great, his greatest strength is his sustain. By mid and late game its ridiculous. He's a fantastic tank and as a third or fourth item you can add in a BOTRK for respectable damage.
