IMO the single best Lv.x in the format when you take into consideration its normal form. The ability to hit for 20 for 1 W (assuming an energy gain) and swap with a bat is an amazing game changer. The main attack is going to be Pearl Breath, which nicely sets up several other options in a good Palkia deck. Hydro Shot is really the icing on the cake. Take that attack away, and this would still be a good card, but with it, its insanly broken. After a few turns of Pearl Breath Hyrdo Shot is evil, and considering that any good Palkia will run mutiple Crobat, this is the single best snipe deck in the format. It's power is probably what really brings Palkia to BDIF status. The fact that it also limmits your opponents bench is really just an added bonus. Anyone who thinks that we Palkia users, use Lost Cyclone to hurt thier set up are sadly mistaken. With this power you can fully abuse the heck out of comming into play powers, such as Uxie and Mesprit. With its ability to consistently get out quicky and rush your oppoent, lock their powers for turns on end and snipe like theres no tomorrow, this really is an amazing card. BTW, Legos actually does run a 1-1 Dialga.
BCIF, and when buit right BDIF.
