The Lord of Pain

(20/09/2024)
The Lord of Pain's last ability must target a player other than the one who cast the spell that caused the ability to trigger. That means that if it's just you and one other player in the game, you'll have to target yourself when that player casts their first spell each turn. (What did you expect? You summoned The Lord of Pain!)
