Getting Plaguetouched Battalion is not a bad idea.
The Meta is Shootcasts, Shootadron, Shootinodons and Shootzneetch.
They want to shoot first and they want to shoot twice. That is why they go for 1, 2 or 3 drops because of this one simple rule : if you roll an equality, the first player gets the double turn.
So, unless you play Archaon and you get your Dark Prophecy, they will have this +16% chance of double shooting your ballz.
My suggestion is, praise The Sacred -1 hit of Daddy Nurgle, get 1 drop, ram their a**, enjoy the Anti-meta smell of Victory.
