Forget about Greninja. 4-4 Frogadier line with 2-2-2 Butterfree (GEN), and Super Scoop Up, Devolution Spray, and maybe Hydreigon (CRI). No energies necessary.
Why did we get that 60hp Fennekin? The art sucks, the hp sucks, the attack sucks. If they're gonna do that they might as well make it an interesting pokemon. Give us a Dunsparce with bad art, hp, and attacks. At least it won't be entirely boring.
Those are all things I gathered looking at the card. You still lose 3-4 energy every time it's knocked out. You either get the benefit of Strong Energy or Cell Connector, you can't have both. Land's Wrath is only 130 meaning you need Diancie Prism Star (or two Regirock EX) and Choice Band just...
Zygardes GX attack is only good against certain decks, the damage isn't amazing, and the attack costs too much, so why does anyone think Bonnie's good?
Diancie and Malamar are both super cool, but my heart belongs to that Alolan Exeggutor and its stupid attack. Single prize attackers with cheap attacks that two-shot everything are great. Maybe with Leafeon-GX and Promo Lurantis.
