We shall see! (i'm still looking out for Moritarion and Fulgrim models...)
Anyway, Magnus is a good-get. He is getting hard to find at a reasonable price, and unlocks a lot of options for me to field a decent sized Tzeentch force.
I went with the 'red' style of paint job for him, which i think i prefer to the 'blue-space-monkey' look of the GW 'Eavy Metal one.
Along side him as another Keeper of Secrets for Slaanesh. Shame its the same sculpt as my other one, but i couldn't find the alternative one and it came in a job-lot.
It also gives me some more options for larger Slaanesh forces, so handy to have regardless!
