Evenhanded Katra Combo + Severin

Credit goes to this deck from Tangellos:
Insert Clickbait Title Here: Evenhanded Katra Combo

This Version has an added Severin, the Mad Mage, giving the board a bid more width, with the possible Rings he can attach you.
Also i swapped Razorquill for Belligerent Yeti, because he can basicly do the same with Infused Strike casted on him. I also preferred Belligerent Yeti over Razorquill, because it can target any enemy, which can be of help in early game matchups, to get rid of early aegis on units or nasty 1 health stuff.
The combo now need one more card to pull off, Infused Strike, but as its a fast spell, it can be a lifesaver against Aggro decks, providing you with some extra lifegain.
So the main Gameplan is still to pull of the infinite Combo, but as a plan B, it can just spam the board with units (Amber Ring), push damage on single units (Emerald Ring), enhance dig draw (Cobalt Ring), use breakthrough attacks (Granite Ring) and/or boost Katra (Amethyst Ring)
