Lightning Talisman procs on self-inflicted damage, tried it for myself. Not sure if the devs planned for this, but if the opponent doesn't have any creatures on the board, trying to proc Lightning Talisman doesn't use one of its charges which is weird to me.

And yeah, I think ultra-Aggro War just doesn't work very well now; I tried a few games with it and usually got rekt. 4-mana Crystal Rain is a bitch 😂
