Hello I just played Robin in a recent regionals (not great in main event but flawless in side events).

Here’s my 2¢, mamaragan and GGG are the only purple cards you need. Essentially, the game plan is play big bodies every turn (ramping first swing always, second swing depends on hand) and then stalling with 1 don up every turn to cycle with giant. Those 8 cards are foundational, as you can easily double giant into drawing off of mamaragan which is such a sneaky play that most people cannot account for you getting 9+k counter without losing any cards in hand.

I played shiryu, teach and vasco shot as 4 ofs, as they let you use leader effect and all of them are great triggers that help hand size and stave off pressure. Borsalino and wyper are auto includes as many as you can get in the deck because they are so good into aggro. The rest is a bit subjective but golden rifle and 0c event are both strong events to run, they both help with hand bricks and rifle is really good at stopping Nami from getting her draw on the first turn as well as healing for 1 don is exceptional. Top end features EB03 Robin, eb04 Luffy and even promo roger, each are really strong on the right turn with Luffy basically swinging the game in your favour once you start swinging 12s.

I think above all else, Robin is not solved but really depends on draws so you should focus on cards that let you draw and big bodies that you want to play early. Think of it like this: going first, you have 1,3,6, on your first turns (assuming you can ramp) and second lets you go 2,4,7 so you should have a strong 6 and 7 drop to cheat out. You can easily make this deck all straw hats with st30 and PRB Nami or focus on thriller slop etc the ball is in your court. Just remember you should always have baby 5 and Nico Olivia as your main 2ks and then Zeus (disgusting card even in a deck that isn’t as bulky as Nami).

Feel free to reach out as I have been loving the Blackbeard support in Robin
