Self-Proof Marshadow

This Marshadow is relatively niche as it lacks both the speed and power to break into the mainstream. However, it fulfills a very specialized role of being a Self-Proof sweeper that has the capability to hit basically everything in the game. Still, one must carefully consider if this Marshadow set is the best fit on any given team.

You can use this Marshadow the same as most other sweepers, try find a way in by switching it in on something passive or predicting a switch. From there, Spore everything (except Kartana) and hope for decent sleep turns. Due to its phenomenal STAB's there is little that resists both of its attacking moves. Like with most niche offensive Mons, Marshadow really prefers having rocks or other hazards up as it will miss crucial damage thresholds without them.

Do not expect Marshadow to consistently OHKO any defensive Mons at just +2, you must be prepared to setup to +4 or in some extreme scenarios, +6. Marshadow is not susceptible to the most common priority (FakeSpeed Slaking), but does not deal well with random SSneak and Aeri/Pixilate FakeSpeed. Still, if those threats are taken care of, Marshadow has the capability to fully sweep a team as it can't be stopped by even Imposter. Thus, if you want to use Marshadow, consider using it on a team which desperately needs a Wallbreaker but also can't fit an Improof for one.

As mentioned previously Marshadow has serious power issues meaning that you will lose to almost every common Wonder Guard 1-on-1 if your sleep luck isn't good enough. This problem is exemplified with the rise of Magic Coat and Spectral Thief on Wonder Guards, both of which will immediately neuter Marshadow. Finally, as is the case with all offensive Mons, you must play carefully around Innards.
