So I just wanted to make a deck with Palossand and here is my list.

Palossand - If you lead with Sandygast, it's typically a good idea to get Giratina up as soon as possible in the back while you tank. Ideally I prefer to lead with Giratina for a quick powerhouse that when fainted, Mars becomes a Powerplay. If you do lead with Palossand, it's wise to gauge your options with Acerola. Can be an efficient way to get healing out of your opponent. Odds are you will not have Palossand ready to attack, so letting him face tank for a bit can stall long enough to get Giratina going.

Mars - As above, it's a solid card to blast the opponent with after a Gira knock out.

Leaf - Great to swap either Pokemon as they both require 2-3 to retreat.

Acerola - Turns Palossand into a menace.

Sabrina - Good for stalls or cheap knock outs.

Finally as always this is just a fun deck. Def not top tier competitive. I hope anyone that tries it out enjoys. I will say it has been very good against the Ninetails event. Enjoy!
