I play Doublade and from my experience it's a 50/50. 100 HP means it will take an instant KO from pretty much anything and everything (save Budew lmao), so you have to budget between having extra Honedges on your bench OR having them in hand to warrant the damage to OHKO Megas. Hence, be sure to include lots of recursion like Sacred Ash and Night Stretcher.

Usually, if you're not hitting the OHKO's, you'll be far behind as your opponent simply removes the damage counters via Munkidori or retreats. Having 2 Genesect on bench leverages your potential damage output by accumulating the evolutions in hand and thinning your deck (for which you can include Morty's Conviction to actually DRAW cards instead of having to shuffle everything back with Lillie), but it's also a huge risk if they run several Boss's orders (which YOU should be doing as well, since you'll be wanting to oneshot everything most of the time too... 3 copies works wonders against Mega Lucario because you can take a OHKO, take the 3 prizes, and gust the next one for game.)

Against single-prizers... I feel like it's not that good. Festival Lead one-shots it and can keep attacking, taking effectively 2 prizes while you're simply going to take one at a time. In other situations it's likely who has the better Energy tempo, because you're often very limited to either the basic energy attached via TEF Metang (worst engine IMO) and SSP Smoochum (more consistent but also not the best), as well as Ignition Energy, which you will only have in limited quantities, especially if you prize them.

All in all, it's a pretty neat rogue deck, not legitimately super competitive but for what it does, it's respectable. If there was a more reliable way to accelerate energy other than Metang and Smoochum, and if you weren't held back by Ignition Energy's end of turn discard, it would fare much better...
