>>433469704x vs seeker is basically mandatory, the team flare battle compressor is good to have, and the Pokemon Ranger supporter will ensure that ADP doesn't shit all over your day. Other than that Shaymin EX is nice to have but hardly mandatory and other than that it's entirely up to you how you build your Expanded deck.
If you want the most bling things possible that show off you have more money than sense, make every basic energy in your deck be a SR golden one, use the SR golden ultra ball from the Plasma Freeze set, and have one of the now incredibly difficult to obtain deck boxes / card sleeves like the Druddigon deck box / Gourgeist card sleeve for your deck of choice. Tropical Beach stadium cards too if you like.
