*Notice* - This deck has not taken me to masters yet this month! I spent most of the time since S4 drop casually playing around with decks and waiting for the Meta to iron out before making the push. Currently pushing through Plat with a better than average success rate.
I originally made this deck as something to combat a lot of the growing meta trend. So far I've had many successes against Praxis mid, tokens, mono time, Blitz, feln (both scream and mid), and skycraggro.
The idea behind the gameplay is to stabilize the board early using a mix of Kothon and control cards. Mid game lay out some mirrors to gain the advantage and weapons to both buff and control the board. Even against most Time decks, you shouldn't have many issues.
The synergy between riders and gleaming shield is crazy. So don't worry about them popping the aegis early game. Use it as a blocker until you can drop gleaming shields to give it aegis again and make a copy. Mid game feel free to copy whatever is needed. Commandos for pressure, Svetya against spell based decks, hell even a merchant if you can't draw one but need one.
The only possible swap I would really suggest is Horde Plunderer. If you have 4 or want to burn the stones on them they would fit well to make it more cost friendly. The dusk raiders fit in well giving berserk to your fliers as well as giving you the card draw however, they are more interchangable in my opinion.
As always, decks are constantly changing and evolving so if you have some feedback for me I'd like to hear it!
