Thought we could discuss some cool lands you can tutor through the knights ability
{Knight of the reliquary}
Just need to remember what we're talking about ;D
Hm the only obvious thing i can think of is saccing the land after you tapped it ^^
but maybe you could run it with {Dakmor salvage} and {prismatic omen}?
There's a land that gives all your creatures protection from a color but I don't remember what it's called. Also {parallel lives} with the land that makes a plant token when it comes into play. I played a really lame knights deck that abused the land that came into play instantly. Also, {crucible of the worlds} so you can play the lands after you sac them.
Evolving Wilds into forest, sac forest to knight for {Arid Mesa} or similar, sac that for a plains and voila, 4 landfall triggers in one turn
You can replay the lands so you don't mill yourself and keep saccing them to the knight. And yes, I would play {Avenger of Zendikar} for the landfall effect. {Cloudshift} would work great since you're playing white already
I liked using {Flagstones of Trokair}. Works great with {Harrow} too!
I once ran a junk colored Titan deck. Had two grave and primeval and three sun titians. With two Ulamog, the infinite gyre. It ran three {sejiri steppe} , two {eldrazi temple}, and one {eye of ugin}. It worked great with the knight, I could search out
The eldrazi lands or swing with a fatty and bring in the steppe for protection.
