So I got to play a few games. In the 3v3v3 draft, nothing remarkable happened. I just picked some high def gladiators and went from there.
In my first 5v5, I went with Zahra, Sereqet, Thoth, Tiet Khebi, and Ur Kek. The star was easily the mounted Combo. Zahra can pull guys in if Sereqet isn't in range OR she can go second and get a reposition for the pair. They ended up doing a lot of work. I didn't get Thoth involved soon enough though since Sereqet was able to activate over and over due to second wind and repositions.
The last 5v5, I decided to run Anum, Proximo, and Acerbus as Beastia. As you saw in Chab's post, it went well for me. I love three Acerbus model but I don't think I got the most out of him. I know folks generally say Mori benefits are better than Beastia, but I'm not convinced. Alpha is really strong. You can get a lot of back to back actions with one of your monsters. Mori benefits are only during a clear turn.
I considered moving that last part to the Beastia conversation, but five dudes on the forum will read it here.
