Thanks. So compared to the Orc/Skaven list Clamatius and I have tuned, you are:
+3 Followers of Mork, +3 Squig Herders, +2 Rock Lobber, +1 Basha's Bloodaxe, +2 Waaagh, +3 Veteran Sellswords, +1 We'z Bigga
-3 Deathmaster Snkitch, -2 Rat Ogres, -3 Greyseer Thanquol, -3 Clan Rats, -3 Orc/Chaos Alliance, -1 Chaos/Dark Elf Alliance
In general, your deck will be slightly faster on average in this matchup (though less explosive - more on this in a moment), and substantially more vulnerable to Flames of the Phoenix.
Your upside is you are more likely to be able to eschew building up a resource/draw engine in favor of aggression, because your 2-dorks can be played to the battlefield, whereas we're running alliances in those spots. On the flipside, you will have draws that flat lose to an early Flames of the Phoenix, and it will be very difficult for you to recover from a mid-game Flames as well without a lucky multiple-Warpstone/Village draw.
Regarding explosiveness though, I think cutting Greyseer/Clan Rats actually dramatically hurts your win % in this matchup. Playing Greyseer and swinging for 8+ on turn 3 is a major reason for our build's wins vs. bolt thrower, and even though I think your deck has the potential for slightly more aggressive draws on average, aggressive consistency is not what you want vs. thrower - you want high-variance, overpowering aggression. Point is, if you are goldfishing kills on turn three or four 50% of the time and slow as molasses the other 50%, that gets you a pretty good shot at a ~50% winrate vs. thrower. But the curve drops off fast... consistently goldfishing on turn 5-6 gets you a roughly 5-10% winrate vs thrower (your wins coming when all 3 of their flames are in the bottom 10 cards of their deck, etc.)
So, have you tested this vs. a well-piloted, well-built thrower deck or is this just theory? Because we have tested most of these cards, and while I will grant you Sellswords is a nice plus vs. bolt thrower (though pretty bad in an Orc mirror match...), I am not really seeing anything else here that offsets the loss of the Greyseer/Clan Rats Skaven package. Rock Lobber is interesting tech we havent tested, but seems beatable with good development management if the thrower player is aware you have it. Definitely something to try.
Not to mention, your lack of Deathmaster or an answer to Deathmaster anywhere in your 50 makes this... not a deck I would choose to play...
You mentioned having an updated list though, so maybe...?
