Leviathan will become legal at our next tournament in December, so I would try some new things from it.
Opponents will be mostly
MSU marine variants and a bunch of
CSM, with 3 necron and 2 eldar players leading the rankings.
CAD:
2 flyrant 2x240
Venom 45 (chasing skytyrant to give it shrouded)
2x3
DS ripper 2x45
Carnifex with 2x
dev in spore 225
T-fex with acid and ESG, in spore 265
Skytyrant:
Flyrant, obliterax, 1x devourer, ESG 275
2x10 gargoyle 2x60
Is this viable against mech spam armies?
I don't see much in the way of wasted points.

3 Winged Tyrants should give you a fearsome presence.

If Mech spam is your primary concern, it would be worth it to consider swapping the Tyrannofex for a second Carnifex. I Love Tyranofex, but it works best as a Troop slaying Bullet magnet, and it is not quite as good vs metal boxes.
If you do swap, you'll save some points. Then you can look at economizing on the Sky Tyrant to get enough for another unit of Rippers or the like. (Drop the Reaper, add Bone sword+ Gland...)So either way you should get good value.
In any case, Good Luck! And Good hunting!
