I do intend to create some chaos nurgle bikes

they will be magnetised so as to be;
Spawn,
CSM bikes and Ork bikes. so basically it will look like an ork who nurgle has mutated with his bike to create this monstrocity

then I can simply magnetise some weapons, so dakkaguns, meltas and a
CC weapon (for when its a spawn).
I love the idea of T6 mob with a nurgle bike lord. He will form part of my '4 horsemen of the apocalypse' theme, which is basically 4 ork warboss bikers. Should be a great list

Just need to bring zhandsnark as my warboss, making bikes troops, then its just 2x
CAD for the warbosses and throw in the
CSM allies.
3 warbosses on bike and a nurgle bike lord, all escorted by bikes.
