Playable list

Alright everybody, thanks for the help so far. Here's the list I have

3 Hero of Bladehold
4 Accorder Paladin
4 Memnite
4 Ornithopter
4 Signal Pest
4 Glint Hawk
3 Mirran Crusader
4 Squadron Hawk
3 Kor Skyfisher
4 Quest for the Holy Relic
1 Sword of Feast and Famine
2 Argentum Armor
1 Sword of Body and Mind

4 Contested War Zone
16 Plains

Some questions: Is 20 lands playing it too light? Should I be up around 21-22? Please don't mention again how awesome Stoneforge Mystics are. I know. They are also at least $15 per, which I am not going to spend for a semi-casual event like Mirrodin Besieged Game Day. Take it as a given that I know I should be playing those. I am shipping a foil Colossus and Titan to pay for this deck, but that still wouldn't cover Mystics. I've been through my collection and I think my needs are...

2 Accorder Paladin
2 Memnite
1 Ornithopter
1 Signal Pest
1 Mirran Crusader
4 Squadron Hawk
3 Kor Skyfisher (No, I didn't play during Zendikar/M11)

3 Contested War Zone

Somebody offered to loan me a War Zone in the last pack but I don't know who that was.
