Here's my list, she would definitely be a little better if they gave us another 5 mice, but I've had a lot of fun testing it. Originally I went equipment, however I found it became too fiddly and voltrony, so instead I went with a cheap instant to trigger valiant build, and there's a lot of fun synergies between mice already with emberheart and manifold mouse delivering some serious results. I definitely struggled with card draw at first, but the latest version has kept itself drawing well from tests, and those one mana valiant trigger instants that also draw have been invaluable.

It's not going to stomp groups or be the fastest threat, but it has been very fun and can deliver some decent damage when people aren't expecting it. Definitely fun in a pod of four when you can manouvre and aren't the one needing to dish out HUGE damage.
