Core of the deck is less than $5. Staples are easily exchanged if budget does not allow for them.
Herald in the extra is easy to get to if you have access to the infernobles and can block nib. End board is consistently a 4 mat apollusa, abyss dweller/allomerus, herald, and follow up. souls is both a small world bridge and a card that can proc your inzektor effects.
Tip that can help a new inzektor pilot;
Centipede and dragonfly trigger for ALL equips that are no longer equiped. If you have an inzektor GIGA and access to hornet, you can normal centipede or dragonfly, use its effect to equip hornet, activate GIGA to equip, activate hornet targeting giga to pop. Now you have 3 triggers, two of Centipede or dragonfly (one for each equiped card that is no longer equiped) and one giga. This allows you to chain block 2 summons and can get you 3 summons if uninterupted.
The extra is flexible but I believe right now this is optimal. The rank 4s might look odd but you can easily modulate with ladybug so it is very easy to go into these powerful rank 4s. Borrelsword is my personal preference over accesscode as you can easily make a lot of inzektors and swing for game by switching them to defence for extra attacks.
