Yeti Actually Works in Expeditions

I will explain my card choices here, and I will only talk about choices that I considered uncommon/unclear.

Iceberg Frontrunner VS Powderglider
In Throne, this is a very debatable question where each of them has its own pros and cons. In Expeditions however, Powderglider is just greatly superior. There are a lot more flying units in Expeditions. Even randomly shutting down a Wind Elemental from Emblem of Kodosh can allow you to gain massive tempo. Also, there is a cute little thing you can do, play Thudrock's Masterwork and play Jump Kick on an enemy unit to give it flying, then stun it with Powderglider. The fact that it is secretly one cost 3/4 when you play the site is what makes it amazing. Iceberg Frontrunner is too low impact for me, especially without Wump, Party Starter in Expeditions format.

Iceberg Shineefinder
This card is just alright, not great but flexible enough to play 4 copies. 3 cost 3/3 is not that great but serviceable, pledge is super nice and super relevant. Honestly, he is just here for being a decent 3 cost Yeti that you can occasionally play as power. We take what we can get! Other replacements include Cloudsnake Harrier which is a much better card, but hey, it is not a yeti. So you can play it if you like.

Ruincrawler Yeti
Basically a Permafrost breaker. The problem with this card is that he is too weak if you do not destroy any attachment, so I think 2 copies are just right!

Chunk Chunk
One of the best, if not the best unit in the deck. Against aggro or tempo opponent this card usually wins the race. You can even sometimes help your team to dodge Malediction by trigger renown on him.
