Dwalin, Living Weapon
deck Dwalin, Weaponmaster
In this deck, Dwalin buffs a bunch of cheap living weapon like creatures to create a wide board that gives you presence during the early game. Then, around turn 6/7, you'll be able to start attaching many of the now buffed equipment to a single creature at the same time for some very powerful swings!
Cards like Mandibular kite that lack a bit of board presence can quickly turn into a 3/1 flyer for 1 mana if it's on the board when Dwalin enters and Dwalin manages to get a single attack off, turning it into a good blocker during the early game.
It's also very fine to trade with these creatures since the buffed artifact sticks around to be equipped later, giving any creature +3/+1 (minimum) and flying!
A lot of the interactions in this deck are also based on equipments, such as Coral Sword and Celestial armor. While these cards usually are a bit below average in power, once they're on the board they can quickly gain a lot of power from Dwalin and continuously grow more and more powerful.
Around turn 7, it should absolutely be possible to drop one of the cards that put all equipments on a single creature (Thorin, Beatrix, Inventory Management & more) to do a big swing for 20+ damage. If all of these are put on Dwalin, it could turn into commander lethal, especially if the equipments you have on board give your equipped creature Trample/Flying/Double strike/ An additional combat step.
All in all, it's a pretty simple deck (as it should be for a precon I think) that lets you be part of the board during all phases of the game. I also really like Dwalin as a commander since he only costs 2 mana. Even if he is destroyed once or twice it isn't unreasonable to cast him again, especially since he immediately buffs the board when he enters (which later in the game could mean +10 power or so amongst all your equippments).
