I hope Ash does lose here now, it would make sense to build Marnie up.
The Gengar Dynamax arc was much better than the one off ep of Lucario getting a Megastone. If anything the Gengar arc along with its bond with Allister was doing a power up arc right.I already complained that Gengar getting G-Max felt like a washed-down rehash of Lucario's Mega Evo plot. His G-Max debut happening in a one-on-one in a potential one-off ep isn't helping change my opinion. But hey! Gengar being alone means no one can steal his thunder for once.
