Icaria Blue ft. Shelterwing Rider

iBlue is in a pretty good spot right now.
Hailstorm was a very powerful addition and it pairs best with other damage based removal such as Torch and weapons (Auric Runehammer and friends). This makes FPJ control the perfect home for the card.

The other thing that's new about this list is Shelterwing Rider. Since it got buffed it is easily one of the strongest cards in the game. Having a flying blocker is a really welcome addition, especially against Haunting Scream decks. Against Aggro it blanks one of their creatures even after they cast a removal spell in it meaning they have to overcommit into your board clears. It fells like having an Eye of Winter with no activation cost. Versus midrange it blanks their Runehammers. Oftentimes you can start pressuring your opponents much earlier than before. Worst case it eats a removal spell that would otherwise have gone to Icaria. Simply having more good targets for Icaria's +5/+5 buff also means you have less games where you lose while waiting to draw your buffed card.
Overall it's been really good.

Getting to masters with this has been pretty easy, there are basically no matchups that I dread but lots of matchups where I feel favoured.

For a more budget version try cutting the Starsteel Daisho and a Sword of the Sky King for another Shelterwing Rider and another Throne Warden.

I think Thunderstrike Dragon is also interesting but at PPP the mana becomes too bad for my taste.
