Try using the autocard feature, just put [c ] and [/ c] around the card names.
With Planeswalkers, you really don't need 2 versions of the same, choose Elspeth, Knight-Errant
over Elspeth Tirel
as you can't have both out at once.
Also what format is this for? Standard, Modern or Legacy?
Off the bat, if you want to play knights in Modern (I only know how Modern knights work as friend plays them) you must have 4 Knight Exemplar in your deck, when playing with them,
(Edit: Missed those in your deck) you need 2 of them out at any time. That one card makes Knights super strong. Kinsbaile Cavalier
is major booster too, giving everything Double Strike is simply amazing. Mirran Crusader
is another popular knight choice.
Equipment is also thematically appropriate, Loxodon Warhammer
and Behemoth Sledge
are good for Knights getting you trample and lifelink, which goes good if you have Knight Exemplar
and Kinsbaile Cavalier
out, turning the basic 2/2 Knight into an indestructible 6/3 or 4/4 that swings for 12 or 8 damage that can't be Chumped (Chumping/Chumped/Chump Blocking refers to the idea that you can stop a 10/10 rampaging living god with a 1/1 sewer rat and take no damage from it, unless it has Trample) and heals you for that much.
Splashing Green means you can play Knight of the Reliquary
which is very good knight. He can fetch those Kabira Crossroads
, fatten up and basically act as you big hitter.
His ability may sound oddly counterproductive, but it actually achieves a purpose, it "Filters" your deck, that is to say it removes cards you won't be needing or aren't as importants as other, as once you can pay his mana cost you can afford everything else
, (EDIT: Forgot he was only GW1, thought it was GW3) so drawing a land means your not drawing another creature to play that turn. Playing Land every turn is essential for say turns 1 to 6 but at turn 7 you won't be needing land you will be needing something to deal damage. So by removing land from your library you increase the odds of drawing more knights to attack with.
The Knight deck from the Knights Vs Dragons Duel Deck is actually pretty good if you want to start knights, but beware despite being good it has some horrible cards like Lionheart Maverick
EDIT: Armored Ascension
pales in comparison to Angelic Destiny
despite it being a Mythic Rare.
