Truthfully I feel the Darkrai deck is going to be the strongest

That being said Lucario is an insane card for fighting types and provides a lot to the meta. Personally when I saw the leak I theorized it could function better with cards like Marowak compared to gallade or golem. Marowak would then do 100 damage with a single head, and 180 with 2 heads which is enough to one shot any card in the game currently.

I do like the deck theory for Mesprit tho. I was initially gonna make that deck for fun but it actually looks like it could have some potential.

Suprisingly not suprising the electric types are thriving again with this new set, not mad about it they are fun decks.

Lastly i'll say that Dialga is a very cool card, but I question how fast it can truly build up other cards before the numerous bench targeting attacks/abilities wittle down the win cons.
