This is a deck you can run for fun with some capability to be competitive as well. The focus of the deck is around using alarmobot to get strong minions out early. Paladin is probably the only class that can pull this off well as they have conditional ways to protecting alarmobot. You can set up a redemption prior to needing to summon it, place down a shieldbearer to prevent minion damage on alarmobot, or by turn 4 (unless you have coin) you can summon alarmobot with divine shield or noble sacrifice.
This does have other plays you can make though that do not require alarmobot if you do not have it. Nat Pagle can give you card draw to potentially get you alarmobot as well as making it easier to summon Mountain Giant per card drawn. Blessing of Might can be applied to shieldbearers or pagle to allow for some early board control while you work into the late game. Overall though alarmobot should be effective since only three minions would be unfavorable to summon compared to other 14.
