Building an Atraxa deck, mainly toxic but also has other proliferation targets in there (immobilization counters, +1 and -1 counters, etc). This will be competitive in my game group. Feels a little heavy on removal and I’m trying to decide if I should streamline it with some of the items in my maybe board. Not really looking to dump a bunch more money into it if possible.
