So I've just acquired a whole bunch of Tau Crisis Suits via the eBay, and am merrily building up a "just because I like the models" Tau army.

And then I saw a picture of a Sontaran, and remembered I already have a Davros figure, and then thought: hmmm.

The Tau can ally with Chaos Space Marines. So what if:

1.) Get some Mantic Forgefathers, convert some potato-heads, and suddenly I have Sontarans who count as CSMs.
2.) If I make a 40mm scenic base for Davros so he can "Count As" Typhus, I can then get some zombie figures from any of the eleventy billion companies currently doing them, create some forehead eyestalks, and bing! Zombie cultis... I mean Dalek Nanogene Puppets.
3.) I already have some of these: [url]http://www.amazon.co.uk/Character-Builder-Dalek-Army-Pack/dp/B0055QHSCC/ref=sr_1_10?ie=UTF8&qid=1352245994&sr=8-10[/url] and they fit nicely onto 40mm bases. "Counts As" Obliterators.

My Tau army suddenly has a whole bunch of Doctor Who allies. Strikes me as just right, really.
