Quadrouple the Pink Horrors, Hit them with pendulum and get 40 Blue Horrors out turn one. It’s a one drop so you can pretty much guarantee going first and flood the board with blues to screen of the opponent with blues and endless spells. The changeling is easily the one loose card, he is a fun trick to deploy behind enemy lines to threaten a purple sun or deploy him just on the border to change in a group of pinks turn one and get that objective. Against hordes he is probably best changed to a Gaunt summoner, if you can afford to go down to a two drop (whoooo scary). Gaunties spell scares the shit out of 120 rats. the 20 points you get left with together with also dropping the gravetide gets you another powerful endless spell like the Shards or quantity in Jaws and Maelstorm. I know Maelstorm doesn’t sound perfect in a spell heavy list like this. But if you get it of with the changeling or the horrors in the frontlines, you can then move back and just let it fuck with them. Its another thing on the board to worry about for all, and you’re opponent is probably going to be more worried about dispelling and moving the damage or the movement-spells anyway, so why not? It’s ten points! Against armies with absolutely no magic, just don’t cast it, or cast it and let it dispel a couple of mystic shields and arcane bolts to load it up and whoops, its a threat again! Oh, forgot. If you switch the changeling you need another unit of brimstones to fill the battalion, but then you can actually give the gaunt summoner the arcane sacrifice and maybe skip the pendulum, so you get a bit less horrors turn one but you still get a shitload of spells of, Gauntie gets two instead of the changelings one, so thats pretty neat, and with him on a Balewind with arcane, you have a 33″ threat range (18+6+9) plus however you deploy the Balewind, plus minus 3″.
Cheers, Kudos and humble thanks to Darrens List Diary for the inspiration and list insights!
