This is my current deck, I enjoy to use. Is quick flow lock down deck based on knights, and provides me with of protection, counter spell, exile... Game I usually won with unblockable 7+ strikers.
I am having hard times against black deck, that force me to sacrifice my creatures, and I think blue counter deck, would make me suffer too.
Pleas comment, I'll appreciate.... just keep in mind I really enjoy fast deck, so I would like to try avoiding high CMC cards
STRATEGY:
For small amount of lands in deck, I use Knight-of-the-white-orchid, or [Path to exile] if really necessary. As soon as possible I play [puresteel paladin], which allow me to draw additional cards, with playing low CMC equipments. Once I have 3 equipments in play, [orge's-cleaver] equip cost becomes free, and combining it with [whispersilk cloak]...
While aiming for upper combo, I usually already played [knight examplar] and [paraiah] on one of my knights, which protects me from harm. Kinsbaile-cavalier is just a fun to play, watching face of your opponent, when they think they are winning with 20life against you 4-8 left, and you all suddenly one hit K.O. him :)
Instants in deck are mostly just to back up, against creature destroyers, counters, damage...
I was considering putting in [wrath of Gods], but than I should increase amount of lands in deck also.
