Description
The card was at $50 in 2013, and is at $35 today
What surprised me even more, though, were the number of decent mana rocks at common

That plays quite well in a Voltron-style build where you make your Tanazir bigger and also makes your Hydra and similar X creatures bigger as their base is normally 0/0 so you get a +4/+4 effect to them without shifting the power of the founder of the Quandrix School

It's a low opportunity cost card that can help sink excess mana into a great static effect, with level three offering an alternate win condition in the same vein as Young Pyromancer without the same level of investment or vulnerability to common removal spells
