Notes & Combos

1 card combos:

Machina Gearframe: NS Gearframe, search Unclaspare, summon unclaspare via its effect, mill Citadel, use Skill effect 3 to send Gearframe and Unclaspare to GY and search 2, then use skill 2 to search 1 more and mill 2. You are usually searching Metal Slave, Regulus, and Derringer Core and milling Citadel, Ruinforce and Gizmek Orochi

Machina Redeployment: Same line as above, but instead of milling Citadel, you add it to hand and mill Fortress instead. Use Fortress to send Citadel to graveyard, then use skill to send Fortress and Unclaspare to GY. We keep Gearframe on field cause it can equip itself to another machine.

Derringer Core or Metal Slave: Use skill effect 2 to add the other to your hand and summon both of them with their effect. Use Derringer Core's effect to summon Blaster Core and use skill effect 3 to send it to GY and search Regulus for negate/

Usual turn 1 board: Metal Slave + Derringer Core + Regulus in field, Blaster Core + Gizmek Orochi + Citadel in GY. Negate with Regulus first, then summon Blaster Core during the opponent's turn with Derringer Core. Blaster Core is EARTH so if you pop it with Metal Slave, it will also trigger Citadel. Gizmek Orochi is insurance, but if you're confident you can survive the turn, you can just mill Ruinforce instead.
