This is my take on a Runick Magical Musket decklist (as an attempt to look for more "fun" alternatives to pure Runick Stun) with the ability to pivot into (or from, up to you) a light floodgate strategy (side out Droplet, Dispelling, Smiting Storm, 2 Link into the VRAINS and one other card for your continuous traps in your side deck)
Otherwise I decided to main deck Super Poly since it is basically the strongest disruption in the game that you can run.
As for the Link into the VRAINS rules: If you can resolve this card it seriously ROCKS. There is about a 10% probability of opening it with another Musker Monster but when you do, your Max effect to respond to an established board will literally not be negateable unless your opponent flips skill drain in response to your spell actvation (might be smart to side this for game 2 with DRNM and Evenly instead tbh since DRNM ensures it will go off)
Otherwise the deck will attempt to simplify the gamestate until you can confortably outgrind your opponent and believe me, from turn 3 onwards your hand rarely stays empty (you might even have to constantly discard Runick Spells because your hand is too stacked which in turn enables larger draws from Fountain during the opponent's turn)
Hope y'all like the list
