Rainbow Guard

Knight of Flowers and Laughing Storm don't go well together, try non-kneeling Loras instead. Is Vanguard Lancer there for initiative only? I'd take them out and put cheaper Hedge knights. King's ground doesn't look very useful here... The stag and rose can also be swapped for more powerful Bara events (Ours is the fury), Offer of a peach I'd cut to 2x, it's mid/late game event. Is Renly's pavillion needed?

Did not think about knight of Flowers/Laughing Storm swapped as you suggested, same for Vanguard Lancer. As for King's Ground I put it there for Bitterbridge but what do you think, too circumstantial? Renly's Pavilion is I thought was a decent mid/late game location can give the 2/3 powers you need to win the game a round earlier. Thanks for the advice!

I'm not a huge fan of Renly's pavilion neither. For power rush purposes, I like better events like make an exemple or superior claim. The main issue here is that too many events may be a problem for the setup. If I had to improve a few things, I would say that the king's ground is indeed average in this deck and I would take it out. Brightwater keep does not seem to fit, especially with laughing storm. I would change it and Renly's pavilion for narrow sea. I need your insight here, but I feel like you will have issues marshalling with the current deck. What do you think? Also, I know that it's not in the theme, but I still think that the RotO Melissandre would be a nice addition to the deck. Her effect is powerful and seems to fit nicely. I also like the bastard of Nightsong better than the Knight of flower here: they are both knight, and while knight of flower has a powerful effect, the bastard has an intrigue icon, which is always a good point for Bara, and his effect has just crazy synergies with Brienne. Last small improvement I would make would be opponent's control. It's again not in the theme but I think than (rather than the king's ground for example) milk of the poppy/nightmare can help you controlling the board.

Carth gave good suggestions, only thing I disagree with is keeping Brightwater keep, it's a good location and will give you additional hand protection if Laughing Storm isn't on the table. Consider Oakenshield Port instead of Renly's Pavillion, it can give you more power faster, though it's not setup friendly...

Thank you both for the advice! I'll update the deck soon. As for marshalling I haven't had an issue so far and I played 4 games with the deck. I can see how Melisandre would be very powerful but I'd like not to get out to much of the theme and I'm also using her in an other deck.
