Way too weak, at 2 mana you have a bad celestial flare which isn't that strong as is, it doesn't work as a sac outlet since its a divine verdict variantmaybe if you kill 2x at least then it has some potential, or get rid of attacking clause
I don't think this card is weak. You can sacrifice three small creatures (tokens, perhaps?) and take out a huge chunk of their army. Seems good to me.
