Cruel Somnophage
Millicent, Restless Revenant | Illustration by Denman Rooke Azorius is very much about tempo
In other words: Clues are very good when you get them for free as part of doing something else (attacking with Azula, On the Hunt, playing lands with Tireless Tracker, casting creatures under Lonis, Cryptozoologist), and there are tons of cards that have synergy with tokens, artifacts, or sacrifice
Starting at 40 life makes Test of Endurance much more tenable in Commander than in traditional one-on-one play, but this primarily exists as a backup plan if you dont hit a better version coming up on this list
The card you find here is in an extended-art frame that shows off more of the standard card's artwork
It takes some work with the trade-off being that it requires no mana and can get any permanentreanimating Portal to Phyrexia and Virtue of Persistence sounds lovely
