Todd, one of the regulars at Tower, picked up Circle recently. Specifically, he picked up Bradigus, and he's building his way toward a Tier 4 Wold War list of the kind that the Internet has warned you about. He'd only had 3 or 4 games with it when we played, and still had to proxy some of the models (because Tower keeps running out of Woldwatchers for some inexplicable reason), but he'd already had some good results. And that's not surprising, because Bradigus is good, and in Tier, he's very good.
UPDATE: Todd actually took a video of this game, and said he would be fine with it if I posted it here. It's a casual game, so it's a little long, and I do a fair amount of goofing off and fidgeting, but I hope you enjoy it anyway!
Since this is my first report against Bradigus, and since a lot of people are still looking for answers right now, I'm going to go a little further in depth than usual with my tactical analysis. I'm going to take a good look at Bradigus, then at my opponent's list, and I'm going to spend more time on my in-game planning blurbs than usual.
