This is the Trump Midrange Paladin Deck he was playing on ladder last season to climb. It’s still relevant this season (season 29) and is a very strong ladder deck.
If you drop N’Zoth after cycling your deathrattle minions like Tirion you are going to close out games. It’s a frustrating deck to play against and you’re goal is to stall out early and look for good board clears and opportunities to drop your large minions unchallenged.
