Disclaimer: I will not focus on Art or grammar, unless the latter would make the deck too difficult to understand.
Card Games with Badminton, presented by Chris and Sarah Tenor. This seems like it will be interesting!
Reading through the entry, I actually ended up liking the gimmick and its execution a ton. It strikes nice balance between simple, but with enough curveballs to make it challenging to face unprepared. It genuinely just seems really fun to play against.
I do need to ask a clarifying question on if a player/players would essentially be facing this deck twice? The picture didn't really clarify this, but I got the impression one of the twins is supposed to set up Shuttle Birdie, while the other goes for Birdedore Doubles - and they swap once the plan's disrupted, since Shuttle Birdie seems rather important to the gimmick.
Good job!
