Current Tier: UU
Wished Tier: OU
I'd like to make use of my rights as a human, to choose Yanmega for OU.. (Nevermind, it just matches, because in Germany are currently the choices for the new Federa Chancellor =D). So yeah, back to topic ^^
What the Hell is the reason for putting that big, scary, fucking speedy insect (i'm talking about Yanmega) to UU? Common, a SpAtk Stat of 361, a skyhigh speed after just one Speed Boost it is a threat which everybody has to fear. Even in OU is can cause so much havoc - Azelf, Infernape, Alakazam, Machamp, Celebi, Cresselia are just 6 which not want to face Yanmega, with its STABed Bug Buzz or Air Slash. With HP Ground even Heatran cannot stop it. And just remember it's Hypnosis move. Nobody wants to defeat one Pokémon, because it misses with a move. The only real Pokémon (all Tier) who can do something against this thing are Blissey and Relaxo, Skarmory, Registeel and maybe 3 or 4 more. With its not-to-bad defenses it should survive at least one neutral hit. It can switch in on any Eartquake, Grass Knot, U-Turn too, which are very common moves, to get a Speed Boost and then sweep. So yeah, i'll add now all points, that speak for putting Yanmega back to OU.
! Impressive SpAtk, skyhigh speed thanks to Speed Boost
! One Speed Boost is almost garanted, because of decent defenses / Protect / Substitute / Focus Sash
! Good type-coverage with Bug Buzz + Air Slash + HP Ground
! Hypnosis as a sleep inducing move
! Very useful switch-in-opportunities, e.g. in Grass Knot, Eartquake, U-Turn or Close Combat
His only contra are really 4-time-weak to Stealth Rock and Hypnosis bad accurate. But with a Rapid Spinner the problem with Stealth Rock should be solved. Actually not really everybody has a Stealth Rock layer in his team too.
So, i just can say: YANMEGA FOR OU.
Oh, and just short: Umbreon is too useless in OU, where Close Combats from Infernape 7 Heracross or other heavy physical hits are too strong for it. All a Umbreon can do is really it's role as a Toxic Staller or as a Trap Passer, but as a Toxic Staller in OU, where Steel-Types like Metagross, Jirachi or Skarmory are on the field, it really has not much success.
