We want to win by turn 4. We do this by getting Valduk or Champion out ASAP and covering them with auras/equipment.
Skirk prospector helps in A few ways. First, it means Valduk can get dropped turn 2. Second, if we play champion instead, we can then sac skirk and put an aura on Champion turn 2, putting him out if lightning strike and Abrade range, which is huge.
I have filled the deck with 1 cost equips and auras. If possible, we want three auras and/or equipment on our guys the first turn they attack, which, if the damage goes through, gives the opponent just 1 turn to respond.
Assuming the opponent sideboards in a ton of removal, we bring in Dive Down for subsequent games.
Siren Stormtamer and Dive Down are great, but if you have to leave a mana up for them, you are slowing down your lethal by at least a turn.
By turns:
Mull until you get Champion, Valduk, and at least two-three land. 4 land is too many I think. If you only have mountains, you might be able to play and hope you draw into an island. If you only have islands, the hand better be bomb otherwise or you might want to consider mulliganing.
T1: prefer Skirk. Equipment is OK
T2: Champion. If skirk was played T1, give Champion an aura. If you have Valduk, no champion, and played a skirk, then drop Valduk this turn. If Valduk is in hand ,but not champion, and Skirk wasn't played, drop Siren or equipment.
T3: Equip, cast auras, and swing. If this is the first turn you cast Valduk, we could be in for trouble should they have any removal whatsoever.
T4: if you swung with a 3 auras/equiped guy T3, you swing for lethal this turn.
