So NR Knights still weak but I tried to pair it with siege and its so much better, better than any variation of knights I played.
Idea is to go full siege Round 1 and then Knights round 2, even if you have a card disadvantage, it doesn't matter. This deck can easily 2-0, the only time it suffers is when you really had a very unlucky draw, despite having Oneiro and AA, that's why added Istredd for further assist.
You can go for Reinforcements instead of Margarita, to get an extra copy of a Siege or Knight unit.
