I will once I figure out what Trainer and Supporter cards I should use too. Was also thinking of using Ninjask and Shedinja from the Dragon Blade set too if Giratina EX was better to use. Actually I think the Pokes I'll end up using are Nincada, Ninjask, and Shedinja from the Dragon Blade set along with Giratina and Mew EX, trying to figure out what the appropriate number for each of my main Pokes will be and if I should include anything else like Yanmega or a 3 stage line tbh, probably not though since that could be overkill. If Hydreigon is better then I'll use the Shiny Krookodile from Dragon Blade over Giratina EX and the Nincada line. Also gonna need a trainer or supporter that can recover cards from the discard pile as well.
Sorry if that's hard to understand but I'm brainstorming right now in all honesty so I tend to get cluttered up thought wise lol.
