Not your screen monkey (he/him)
Not just a decent fellow, he's also got a some really good DMing skills that can be worth emulating even if your style isn't exactly like his. I've been DMing about as long as Mercer has been alive and watching him still helps me up my game.Easy now with the Mercer jabs. That's a real person you're talking about, not a game mechanic or imaginary elf.
His show is definitely an acquired taste, but from what I hear he's a decent fellow.
