This is not a big deal at all, but: stop using goblins. Specifically, if you are running  a game for brand new players, and they are entering their first ever combat, the 5th Edition goblin statblock, particularly the bonus-action-hide, is very bad at exemplifying the game's fundamental rules. And today, I'm going to prove it.

I'm going back to writing scripts.

I want to challenge your preconceptions about the Deck's effect on a campaign and why players react to this artifact so strongly, and then we can apply those lessons to other magic items.
