“(Insert name of uncommon legend creature here) is good” could easily be a theme in the Dominaria set. But, Adeliz, the Cinder Wind is actually quite good. Even as an uncommon, Adeliz quickly found herself on buylists for bulk rare price or even slightly higher. She also has had a positive demand curve.
Adeliz, the Cinder Wind is a blue/red Wizard that screams Wizard tribal. A 2/2 creature with flying and haste is always good for three mana. Also, her ability to pump all Wizards you control whenever you can an instant or sorcery spell – even herself – works on either offense or defense.
Unsurprisingly, Adeliz has proven good enough to be part of Standard Wizard Tribal Aggro decks at three copies. Even as a Legendary Creature that you can only control one copy of at a time, Adeliz pumps your whole team, so having extra copies in hand isn’t really a problem. You’ll want extra copies of her to drop in case they deal with your first Adeliz.
Adeliz, the Cinder Wind is even good enough that she’s appeared in Modern Izzet Wizards at two copies. There are enough one drop spells that can quickly activate her ability, such as Lightning Bolt and Serum Visions. Even in a fast format like Modern, she makes Wizards a viable aggro deck She’s even popped up in an occasional Vintage Grixis Control deck as a quick source of hasty damage in the air.
With how expansive Wizards are as a tribe in Magic, it shouldn’t be a surprise that Adeliz, the Cinder Wind is also good in EDH. While Adeliz, the Cinder Wind Commander decks aren’t all that popular just yet, they gained some powerful allies in Guilds of Ravnica with Niv-Mizzet, Parun and Murmuring Mystic. She’s definitely one to watch as a Wizard Tribal Commander.
Really, Adeliz is way too good a creature to be uncommon. She’s a solid card for any Magic collection, but also a great card for the Magic card investor binder. As a creature who’s playable in either 60-card Constructed and 100-card Commander decks, Adeliz is really fun to build around and a home run card for Magic players both new and old.
