This is the Sjow Rank 1 Legend Karazhan Dragon Warrior w The Curator list he played on stream to peak at rank 1 on NA.
It’s very similar to the standard Dragon Warrior lists. The new card The Curator has been put in and more beasts added in Fierce Monkeys to be pulled out when The Curator is played.
Sjow replaced Onyxia for a second Drakonoid Crusher so you can do this if you don’t have Onyxia or you’re finding the META a little too fast.
Dragon Warrior has been criticized for being straightforward to play, and it is compared to some other decks. You will have most success when you can curve out into all your strongest minions with Dragon activators. It’s still fun though, and Sjow’s success shows how strong the deck is.
How to Mulligan for Dragon Warrior
This is a tempo deck, so starting out fast is key to winning. Ideally, you want that one copy of N’Zoth’s First Mate, but if you have a Fiery War Axe keep that. An activated Alexstraza’s Champion is also part of the dream start. Keep a strong 3 drop if you have a good 2 drop, and keeping a Twilight Guardian vs aggro decks like Aggro Shaman is fine if you have the coin.
