Heartstone must fun & ridiculous deck: the alarm-o-bot deck.
Tonight I test the alarm-o-bot deck and it is a blast to play when it works :) Basically the alarm-o-bot card, which cost 3, swap at the end of the turn with one of the minion you have in hand regardless of its cost.
The alarm-o-bot deck is build around this ability and basically contains only high-value minions (mostly legendary) and a few spells. It played as a druid as the perfect starting combo is innervate + alarm-o-bot as it allows you to play the alarm-o-bot turn 1 which maximize the chance that your opponent can't kill it.
Usually, as visible on the screenshot were I got Alexstraza out on turn 2, when this combo work your opponent usually concede/rage quit. Otherwise you loose badly :)
So if you play heartstone, give this deck a a try as it is very fun and give you a thrill when it works (like a miracle rogue). #heartstone
