I like him since the rework. He has the highest first-turn skull damage in the game (i believe, not including any spells obviously) once you get the spiked armour trait. Works great with keeper of souls on purple days in GW.
Armour gain is a little underwhelming especially now there are more sky drops. It does seem a bit wrong that his armour gain can get undone in one skull match from the enemy.
Maybe a teeny buff to make him gain some attack as well as armour? Even if it’s like 4x less attack gain than armour?
I’d leave his traits and cost as they are.
