while i appreciate the effort you didnt do much helping. telling me better mons or movesets for the pokemon i want to keep wasnt much use. Sableye is much more useful prior to its mega evolution because of its prankster ability getting priority confuse ray, will-o-wisp and recover, telling me what to run on a pokemon that im trying to replace because its getting banned is a bit unhelpful. I really do appreciate the effort you went to but you answered none of the actual questions i was hoping for.
to clarify for anyone else i want to find replacements for greninja and togekiss. and am unlikely to replace the other actual pokemon that i use.
Non-Mega Sableye can still be used, but it pales in comparison to its Mega Evolution because the former isn't that bulky even when invested, as I mentioned before. The only reason you should use regular Sableye is only if you have a Mega slot taken up. You can always hold off of Mega Evolving Sableye until the right moment. Confuse Ray isn't a useful attack because confusion can easily be cured by switching out.
If Greninja were to be banned, Latios, Gengar, Mega Lopunny, Mega Sceptile, Mega Gallade, Mega Aerodactyl, Mega Diancie and Mega Metagross are decent replacements:

And I'm just wondering, but why are you so keen on keeping Cinccino and Umbreon when they're terrible in OU for the reasons I stated?
If you insist on keeping Umbreon, then use this, as this is a much more better use of its supporting capabilities:
-Wish
-Protect
-Foul Play
-Heal Bell
Nature: Calm
EVs: 252 HP/4 Def/252 SDef
Item: Leftovers
Ability: Synchronize
And if you insist on keeping Cincinno, give it Life Orb; it's not that strong, really.
