so I decided to start 40k and will be purchasing the rulebooks and codex I need over the coming months.
There are 3 armies that really stick out to me, which are skitarii, tau and necron. I decided I want to go with a semi competitive, yet casual, tau/necron list. I managed to get my hands on a box of necron immortals (unassembled), a tau coalition command, tau ethereal, Aun Shi, XV15 stealth suit (single). I wanted these mostly to start a bit of painting, but I'd love to include the immortals and commander in the army at least.
So my question is - where do I start? What units should I purchase next? I want to ideally be able to build a 500 point list first and keep expanding it up to 1850 to be tournament ready in a few months, with monthly purchases of about 100$
I am able to get a doomscythe, ghost arc and tesseract/obelisk super cheap from a friend if needed, but I am not sure if they are playable. I also saw a tidewall for sale, but is that any use?
