Honest question, is this a sarcasm/parody channel? If so, the sarcasm is not that obvious to see. If the suggestions are serious then most of them are not good picks at all for Atraxa. For example, Contempt and Mark of Eviction. You would never want to bounce your 7 cmc commander to your hand to pay 7 mana again just for the etb (on top of the 1/2 for the enchantment). You have access to blue/white and Cloudshift, Ephemerate and Momentary Blink are just straight up better at the same price. Except for Sky Turtle, most other cards are so random or only niche for certain types of deck that you can't really say they are good pick ups for Atraxa. Athreos - good for aristocrats with low cmc creatures and a reliable trigger (sac) Oji - way too restricting. If you want the etb trigger of Atraxa better, cheaper and faster ways exist in these colors Callaphe - there are better ward/hexproof/protection givers at lower cmc and for one mana more you have Shalai/Sigarda As Foretold - you need a spellslinger/flash deck that can utilize the effect on every turn Ana Sanctuary - in a Golgari aggro deck maybe Titan's Nest - in a graveyard deck with a ton of selfmill maybe Urza Assembles the Titans - in a super friends deck maybe
