Arceus, huh? I'm not really quite sure why we're making a counter to that of all things, but I went along with it. Because of the in my opinion unusual 100 HP rule, I decided to give them the status of the ORIGINAL Dark Pokemon from the Team Rocket set; I wasn't a big fan of the half Dark ones in TRR, so I just went with the theme of lowered HP. I tried to make a line that didn't only have utility against Arceus, but against other popular cards in general. Going to go with the Colorless Arceus' Rippling Wave attack, are you? Prepare to get blasted in the face with 140 for CC! Got out the Pantheon Lv.X in my face? How about I slap down a Memory Berry and lock that sucker down? I tried to give the lower evolutions utility attacks like the RR Flygon line has, because I really like the idea of having many different options to use. Thunder Spear and Dual Whiplash obviously combo together to use against bigger setup decks that take advantage of Pokemon like Claydol, while Rainbow Prism has more utility vs. SP decks, which would probably save their power sprays to avoid getting massively spreaded on. This deck would actually be great for people who are tired of Fainting Spell flips!
EDIT: I think I got all the stupid é's... -.- dark pokemon aren't sp/shining/star/ex/lv.X/legend/owners so go me!
