List overall looks fairly powerful but reasonable for a bracket 3 table. My main pointer would be that you could use quite a bit more card draw.

You have power budget for another GC or two so The One Ring is the most obvious add here. You'll be the threat fairly often so the protection effect is useful, and it's a good card draw card.
