There is a legit argument for Aettir and PriwenAettir and Priwen being better, since its still really good even if you draw it late
(You may cast a card for its miracle cost when you draw it if it's the first card you drew this turn.) At the beginning of each opponent's upkeep, you may discard a card
Once this powerful mythic rare rotates out of Standard and the price comes down, I expect this card to find homes in a ton of Commander decks
If you like dictating the pace of the game, and watching your opponents suffer as you destroy every plan they have, this is your deck
Of course in order to have a big impact youll have to have planeswalkers with lots of loyalty to spare (looking at you Karn Liberated, Ugin, the Spirit Dragon, and Nicol Bolas, God-Pharaoh) or have a surplus amount of them
