Ochran Assassin - we can use this, just attack with 1-2 exalted triggers and clear their side of the board. But as a 3 mana 1/1 it's probably too inefficient and unreliable and easily answered.

Crackling Drake - this seems awesome, cantripping flying x/4 creature. If only we played more instants and red.

Knight of Autumn - obvious great card, now we really need to consider if we play this over Qasali in the maindeck. I think at least a 1/1 split, if playing Meren.

Card links are going to show up eventually, I'll use the cards tags already.
