"Lightwheel Enhancements" not castable from graveyard, despite max speed.
For some reason, this aura cannot be cast form the graveyard, despite having enough mana, a valid target, max speed, the proper phase of the turn, etc. It was critical to me winning the game, and I would've been very salty if it cost me.

I didn't think to screen record in game, but I swear the problem occurred how I described it lol.
