Mulligans
Combo: Play two Galvanizers while both Wargears and at least one Replicating Menace is in hand and play Coppertail Imposter alongside the Galvanizers. On the combo turn attach two Wargears (3), and one Replicating Menace (2), onto the Coppertail, then cast Windfury (2) onto the Coppertail for a 17/15 WIndfury mech.
This combo is quite flexible as you can instead attach two Replicating Menaces and one Wargear. Running the quest purely to draw off of Questing Explorer.
