ReshiRom is insane for a lot of reasons. Seems like you could very easily build a deck with 4/4 Lillie/Welder, 4/4 Acro Bike/Order Pad, and stuff like Rainbow Brush, Mysterious Treasure, Fiery Flint, etc. Insane card, most likely going to be a top tier threat when the set comes out because you simply cannot ignore a 270 HP beast swinging for 270 every turn for practically no drawbacks. That combined with the double 170 snipe... But I also think Koffing is somewhat underrated here. Jolteon Star and Crobat G is not Expanded legal, and I've been longing for a card that allows you to place damage counters without having to evolve something (Golbat and Frogadier). It would go really well in something like GiraChomp for example. And damage mods post-rotation is hard to come by. If a deck is playing high counts of Roxie, it seems like 1-2 counts of Koffing is reasonable as a form of damage boost. Shame it's a basic though, since there's always a chance you'll end up starting with it. Magneton is really interesting. You could easily search Surge + 2 supporters in a single turn, or 3/4 hat ladies, or more supporters to discard with SlowDuck. I'm really excited (terrified?) to see what comes of this. Clefairy Doll can probably make stuff like Beheeyem a lot better.
