Like many people I used to use Yeti's to rank up at the beginning of each new season but with changes to the meta I have found that to be much less effective than it used to be.
My answer to this is my new 'we live and we burn' deck. While it maintains the same early tempo with some great yeti's it also uses a combination of burn spells and dragons to allow you to deal with any threat your opponents play, while also being able to consistently chunk them down.
Our market is full of the cards we need to either shut our opponents down or to secure our victories. As burn decks are outside of the meta and rarely played people seem unprepared and often play there squishy minions at the perfect time for this deck to exploit.
Give this deck a go and have fun with it. Oh and when you do please let me know what you think!
