Jayce, Defender of Tomorrow

Jayce, Defender of Tomorrow readies a gear for one energy, and two gear once Empowered. The deck is thirteen cheap gear and the units that get better for each one: play gear, use it, ready it with the legend, use it again. Every gear is a card the opponent has to answer twice.

Mulligans: keep Platewyrm Egg or Questionable Tome, a two-drop (Patched Porobot or Veteran Poro) and Repair Specialist or First Mate. Send back hands with no gear or with two five-costs.

Early game: Platewyrm Egg on turn one or two, and ready it with the legend for a second energy the same turn. Patched Porobot draws a card when you already control three gear, so hold it until the third. Veteran Poro picks up a Doran's Blade or Jagged Cutlass for a rune less as it arrives. Pit Crew readies itself every time you play a gear, so it attacks and defends in the same turn.

Mid game: Repair Specialist has Assault for every gear you control, so with five gear he attacks as an 8. Tools of Empire gives +2, or +4 when Empowered, and Hextech Formula Empowers it for free. Jayce, Hammer in Hand chooses Assault 2, Deflect 2 or Ganking every time he becomes ready, so a legend activation or a Wallop on him is a new mode each turn. Shock Blast costs one with anything Empowered and deals 4 to a unit on a battlefield. Rocket Barrage kills a gear or deals 4 in a base, and repeats for four more.

Late game: Acceleration Gate readies four things at once, your two Eggs, Tools and Jayce, which is a whole extra turn of energy and attacks. Combat Chef lands as a 5 wearing your best Equipment for a rune less. Questionable Tome turns spare energy into cards. Ornn's Forge makes your first gear each turn cost one less, Piltovan Forge makes the first gear ability cost one less, and Veiled Temple readies a gear when you conquer there.

Mistakes to avoid: - Playing Patched Porobot before the third gear - Readying a rune with the legend when a gear was waiting - Spending Rocket Barrage on a 2 Might token - Keeping Acceleration Gate for a perfect turn that never comes; four readies on turn five is already a win
