GO GO TAKE ALL YOUR OPPONENTS STUFF
This is a sweet GO midrange list bolstered with new cards from The Winter War. A small desert synergy lineup lets us make the best use of the powerhouse uncommon Mardykhor. In addition to that you have an awesome lineup of 2x Temptation 1x Murmur and 1x Angelischism which allows you to do some really fun stuff to your opponents cards with Bald Mountain to double the fun.
GO used to be a combination which struggled to deal with threats like 7RR however the new addition of Terminal Calculus gives us an additional out without needing to play 2x Seal of Exile giving us some diversity in how we can deal with threats.
Wry Trickster, Detained and Born Again give us some handy speedbumps against aggro while we wait to set up our line of 3 and 4 drops to stonewall them.
All in all this is a really fun deck with the ability to win against both Aggro and Control when played well with nice hands.
Best of luck and remember to make your opponents cards work for you!
