Atraxa prebuilt deck with some of my edits.
Reasons I'm Playing Cards:
Ajani, Mentor of Heroes - Counters and lifegain.
All Suns' Dawn - Return up to 4 cards from your graveyard to your hand.
Altered Ego - Copying your best creature and put more counters on it.
Ashiok, Nightmare Weaver - A bit of mill, creature advantage, and control all packed into one walker.
Bow of Nylea - Deathtouch, counters, lifegain, and card return.
Deadbridge Goliath - It's my personal favorite card and I can get counters.
Diabolic Tutor - Why would I not put in the most common tutor?
Garruk, Apex Predator - Planeswalker destruction, deathtouch beasts, lifegain, and trample emblems.
Gleancrawler - Card return after an unsuccessful attack.
