Harmonize on barracks? really?
You could just cast a [mwcard=FWJ04]Garrison Post[/mwcard]. It costs the same amount of mana, costs 2 spellpoints less AND allows you to cast your minions in another zone.
One of my decks uses these openings (same deck):
T1: 19 barracks + construction yard 0
T2: 9+2+1 Run 2 + [mwcard=FWJ04]Garrison Post[/mwcard] close to the opponent starting zone 6
T3: 15+5+1 Deploy [mwcard=FWC15]Thorg, Chief Bodyguard[/mwcard] near the opponent + something
Second opening:
T1: 19 barracks + construction yard 0
T2: 9+2+1 [mwcard=MWSTX2FFQ04]General's Signet Ring[/mwcard] + [mwcard=FWJ04]Garrison Post[/mwcard] 3+2
T3: 12+5+1 Deploy Goblin without ring, cast goblin with ring + [mwcard=MWSTX2FFJ03]Altar of Domination[/mwcard] OR Ballista (You could also opt for big guys now)
I plan the same cards in both openings during the first 2 turns, so it allows me to wait and see what the opponent does.
Anyway, harmonize and mana flower seem like cards that could be replaced with more of the warlord in-school stuff.
Just my 2 cents.
