I run this deck with cyber stein and a copy of Last warrior from another planet, and the naturia fusion that infinitely negates spell/traps by banishing 1 card from grave and sending the top card of your deck to graveyard. Against normal decks Last Warrior shuts them out completely, and in the mirror match the naturia monster simply wins the game, as it constantly refuels it's own ability, and can be activated as many times per chain as you want. Absolutely ends the hopes of a fellow Runick player.
You can play synchro runick with punk and fabled engine while sadly deer note hasn't come out yet the deck legitly strong. Also fountain for whatever reason not hard once per turn deserve to be limited.
I'm not very familiar with with Runicks but it would seem they are really pretty reliant on their fiel spell. Perhaps Splashing in Malefic Stardust for the additional field spell Protection and an actual body on board would seems nice.
