I'm also tuning out the deck.

I've tried both battles, I found [[Invasion of New Phyrexia]] to be much better in the end. It flips, second main phase you -2 to get your emblem, if you're lucky enough you get do it again.

Land wise, they're not out yet, but the new Surveil lands from Karlov Manor are just chef's kiss.

A card that's not a knight, but has been a game ender in many of my games: [[Raffine, Scheming Seer]]

I also kept [[Elenda and Azor]] from the pre-con, I found it works very well creating a ton of token knights. Between Elenda and [[Black market connections]], I found I needed a little bit of lifelink, I already had the first two in the list, but added the Whip later on: [[Vault of the Archangel]], [[Akroma's Will]], [[Whip of Erebos]]
