In my opinion the best earth machine build out there. An increased deck size decreases chances of drawing box or unclaspare, while increasing starter count to 14 gives it 85% chance to draw a starter. Including new Clockwork Knight gives interesting lines with Scrap Recycler. Best combo is Redeployment + Switchyard + 1 discard, which results in 2 Super Dora, Knuckle + Bullet loop, Regulus, and Citadel in the gy. Pretty resiliant to handtraps if ordered correctly. Engine isn't bad going into boards, but pairing it with 14 non-engine makes it consistent at breaking boards. Switchyard makes rank 10 plays much easier. Machinas are best into boards, and infinitracks are great for consistency and recursion. Sargas is great on the crack back, where you can insulate otk line with Regulus. Cards are relatively cheap, so this is a budget deck that gets better and more fun with more repetitions.
