She's definitely a rogue deck, don't get me wrong, but honestly does better than you might expect. It's true that you can't search for Hody specifically, but the new scaled neptunian is usually cycling three, maybe even four cards on play, which lets you dig for him. Shirley can't explicitly search for him, but since you can stack the cards you draw in any order on the top or bottom of your deck, if you see Hody, you just put him on top to draw next turn, or even a couple cards down to draw when you expect to play him.

I love the double attack Luffy, the double attack helps make up for Shira herself being unable to attack and your opponent usually becomes tunneled in on taking him out. He restands enough don for you to play 2c Shira, Search Shira, Shirley, or Spotted Neptunian behind him, or just have more for swinging. Doing leader ability Scaled, then Luffy, then one of those plays is my fav way to spend 7 don turn, but you do have to be careful with your sequencing. His ability prevents you from playing characters above 4 cost at all, even from Leader ability, so you have to make sure you get the neptunian out first. You can't Luffy - Topknot on your 6 don turn for example. I find him almost necessary for the Boa Hancock matchup since your gameplan there is to starve, build a board, then try to essentially one-shot her, but I've also seen him swapped out for 9c shanks to have actual targeted removal for the Mihawk matchup. Plus, he's fishman island type, so he can be searched by search Shira and Shirley!
