Advice for starting Maggotkin

Hey everyone

I should start by saying that Nurgle was initially my least favorite Chaos God as I found him truly disgusting. However (rather fittingly) over time a slow cycle of change has morphed my opinion of him as I've learnt more about his lore, and I love how he genuinely does on and "loves" his followers in a way the other three most certainly do not!

I've always liked Mortals more than Deamons so the reveals at the weekend sealed the deal for me! My question to you however is what would be some good purchases to make in the meantime while waiting for the new mortals to arrive?

Many thanks in advance

P.S While I may not be that keen on Plaguebearers and the Hero equivalents I do like the Nurglings, Beast of Nurgle and Great Unclean One
