1x Inspiring Veteran, (in) - 2x Youthful Knight, 1x Dub, 1x Haktos the Unscarred (out)
Inspiring Veteran is probably one of the best Knight tribal cards in standard at the moment. It is literally one of the best knights in the deck. Rimrock Knight is a decent card, and Basri's Solidarity is great. Here, Youthful Knight is not very strong without any buffs, Dub is quite pointless (deck wants Equipment), and Haktos the Unscarred is not a Knight, however good he is.
2x Venerable Knight (in) - 2x Basri's Acolyte (out)
Venerable Knight is an amazing one-drop in any white deck, and even more so in Knights. Basri's Acolyte is just too clunky, and does not have any real Knight synergy.
2x Worthy Knight (in) - 1x Grasping Giant, 1x Infuriate
Worthy Knight is one of the best rares for Knight tribal in standard. It has Knight synergy, and it creates a bunch of chump blockers. Grasping Giant is good, but not the best for this deck. Infuriate isn't bad in mono red, but it doesn't really have a spot here.
1x Acclaimed Contender (in) - 1x Infuriate
Acclaimed Contender is a great card in this deck. A 3/3 for 3 that finds us a Knight or Equipment is great to fetch a Knight, or perhaps an Embercleave.
2x Fervent Champion (in) - 2x Weaselback Redcap
Fervent Champion is, in many ways, a better Weaselback Redcap. It helps Knights, it likes equipment, and it likes to swing in on turn 1.
2x Kabira Takedown
(in) - 2x Pacifism (out)
Kabira Takedown
is one of the new modal double-faced cards from Zendikar Rising. It can be a land, or it can be handy removal, considering the amount of creatures in this deck.
1x Embercleave - 1x Short Sword
Embercleave is busted. It is OP.
1x Maul of the Skyclaves - 1x Short Sword
Maul of the Skyclaves is a great, efficient equipment for this deck. It provides easy evasion and a hard-hitting creature the turn you cast it, because it equips when it enters the battlefield!
1x Shatterskull Smashing
, 2x Scorching Dragonfire (in) - 3x Tempered Veteran (out)
Shatterskull Smashing
is a great card, perfect for large-scale removal. Scorching Dragonfire is some of the best red removal in standard right now. Tempered Veteran just does not do anything in this deck without counter synergy, so it is out.
2x Needleverge Pathway
(in) - 1x Mountain, 1x Plains (out)
All dual-colored decks need their dual lands to have a consistent mana base. This pathway is another modal double-faced card, which you can play either as a white source or a red source.
