I know you're still in prototype mode, but Atraxa is prone to hate and she could use Lightning Greaves / Swiftfoot Boots. Might as wel go big with Teferi's Protection too. Also, if you plan on building this in paper, R.I.P. your wallet...

Those are some good suggestions, thanks! The trick about this not being a bank buster is that I already own all the cards. I started with all the planeswalkers I own in the colours and then filled in the land base and some other useful removal and card draw from the Atraxa precon. I do also have all three of your suggestions so I will definitely consider them too.

A usual suggestion I say is Oath of Nissa

I would add in Teferi, Temporal Archmage

Thanks for the suggestion, Hotspeed. I had also been thinking about how well Teferi would fit. If ever I come to own a copy he will definitely have a place here.

So my wife and I happened to open a Doubling Season in a Battlebond pack! So that's pretty exciting to be able to include. Ashiok, Nightmare Weaver didn't feel like it fit with any of the other synergies going on so that's who is coming out.
