Currently, what strategies do you feel are able to go 5-0 at a tournament? I am starting to prepare for a GT that may still happen in a few months and would like to know what to focus on.
Dracothians tail with mass salamanders.
Fangs of Sotek with skinks out the ass. Probably a few big blobs regular skinks and a few big blobs of chameleon skinks.
Something (probably in dracothians tail) with Kroak+Slann and a billion bound endless spells.
All with the standard kroak/astrolith/balewind combo. The one that rises to the top will obviously depend on matchups and meta.
It'll be some form of powerful shooting and magic with cheap skink screens. It's the most obviously powerful thing in the book, its easy(ish) to play, it's easy to build, it's easy to paint.
I'm not super convinced a warrior/knight list can 5-0 but i'm going to keep trying it.
However, with all that said if you haven't gotten close to 5-0ing in past tournaments and don't play regularly with top players, i wouldn't worry about what list can 5-0 because you wont (only one person will after all

). Not sure what your GT experience is so, take that how you will. I've just found that having unrealistic expectations can really put a damper on the whole weekend. Playing 5 games in 2 days can be exhausting, especially so if you're playing an army you dont particularly like the style of because you thought it was the "best."
