Tyrael’s Charger is a recolor of Celestial Steed, which, is a recolor of Invincible.
I already have Invincible, which I personally think is the best version of the three, and always obtainable for a while now, just a bit rare.
Imo, give us a newer Pegasus mount, maybe. It’s a cool skeleton, I’m sure they could give us some better skins from the modern era- all 3 of these mounts are old now. They just didn’t age as well, Invincible probably the best.
