Kill team

I know it's been a dogs age since I've posted, but life just gets in the way. That and I had to build my 1750pt BT army for the Throne of Skulls in October, so the contemptors continue to gather dust.

I love the idea of a carcharodon kill team (and a Black Templar one if I'm honest), anyone got any suggestions on what to take, go fluffy or serious I'm happy with either! Just fancy getting creative with the scalpel and brushes...

Carcharodons (still using my BT as counts as)
Termies with thunder hammers? Lightning Claws?
I'll get to use Tyberos - nice!
