This is a core I used briefly on an OU team I made a earlier before OR/AS was released, although I have to say it still works admirably. The core utilizes a defensive Slowbro + Mega Venusaur core to handle a goood portion of the metagame by themselves, with Entei slapped on as a glue and generic wallbreaker to help break down opposing cores and stall teams, as well as handle some of the threats that Slowbro + Mega Venu struggle with, such as Charizard-Y, Volcarona, Mega Alakazam, etc.
Mega Venusaur's set is pretty standard, the given EV spread outpaces standard Azumarill and gives him fantastic mixed bulk. Giga Drain + Sludge Bomb are obligatory STABs, while Synthesis lets you keep Venu in the game longer. The last slot in this case goes to Leech Seed, letting him annoy switchins and prospective set-up sweepers and pass some recovery to his teammates. Sleep Powder, HP Fire, and Toxic are all viable alternatives. Mega Venusaur handles bulky Waters, Serperior, Azumarill, bulky Grounds, fast Electrics like Raikou, Mega Manectric, and Thundurus, and Fairies like Clefable.
Slowbro is a little different. It mostly looks standard, but the difference here is in its EV spread. 108 Sp. Def EVs means Life Orb Latios can never OHKO it, even after Stealth Rock damage. This also gives it a substantial boost to its Sp. Def, allowing it to take neutral special hits in a pinch and fire off Thunder Wave or Scald to cripple opposing threats. Slack Off allows him to instantly recover a chunk of HP and works great in situations where switching out to Regenerate just isn't feasible. Psyshock is mostly filler but it's nice for killing off weakened Amoonguss, Conkeldurr, etc. Fire Blast is an alternative for luring and KOing Ferrothorn and Scizor, who can otherwise posit some trouble for this core assuming they're backed by teammates who can handle Entei. Slowbro handles strong Fire types like Mega Charizard X, Talonflame, non-Power Herb Heatran, lures fast Psychics like Latios and Alakazam and cripples them with Thunder Wave, and handles things like Tyranitar and Bisharp in a pinch, being able to tank Crunch and Knock Off and threaten a Scald burn or paralysis.
Entei is the glue that holds this team together. Originally I was using Heatran but that's just super-standard, plus Entei packs two things that Heatran does not; a strong Stone Edge coming off of a decent Attack stat, and Sacred Fire, whose painful 50% Burn chance means even resists want nothing to do with it. Extremespeed allows me to pick off weakened threats and guarantees that if Talonflame beats Slowbro with Sword's Dance it will be revengekilled immediately, thanks to Brave Bird's recoil. It also lets me revengekill Mega Alakazam, a Pokemon that otherwise gives me no end of trouble with its ridiculous offensive presence and insane coverage. Iron Head lets me smash past Clefable and Mega Diancie, who can otherwise give me a lot of trouble (especially if Diancie packs Psyshock to break Venusaur) as well as putting a dent in Tyranitar. Entei glues this team together by removing things like Scizor, Metagross, opposing Mega Venusaur, Celebi, Tangrowth, Ferrothorn, Clefable, etc., as well as revengekilling with Extremespeed.
All in all a fun core to use. By no means perfect, but Entei is such a fun Pokemon to use and finally finding a core that it can shine on is great to me.
