Jellicent is easy to remove and isn't a very threatening at all. All you do is slap Choice Specs on your Chandelure and watch pringles get destroyed. Either that or you just grab a CB Tar and get to work. Dragonite, on the other hand, can sweep pretty much whenever it wants and is definitely something you'd want to get rid of ASAP. Jellicent? I keep it alive so you can set up on it with other stuff, lol.
Just saying for the OP:
- SubCM Keldeo loves Toxic Spikes. With two layers up, all Jellicent can do is stare at Keldeo's fine looking Sub and fail to do anything to it while it just dies from Toxic.
Latias: Latias is about as close as you can get to a true counter to Keldeo. Thanks to its impressive Special bulk and a defensive typing that grants it resistances to both Water and Fighting, it is one of few Pokemon in the tier that can come in and take Keldeo's hits comfortably. Latias can also Roar out the blue pony should it accumulate too many Calm Mind boosts.
Not to mention Latias can switch into anything from Keldeo, even a super effective Hidden Power, even with an offensive spread, and OHKO with Psyshock.
Whatevs sig. QC member for OU and Ubers, VM me for a look at your analysis. Just make sure it's good.
Also, if you want me to rate your team (OU/DW OU/Ubers), give me a VM. If I don't rate it, it's either 1) it's so shit it's too much trouble, 2) I'm busy, or 3) the team is fantastic and I have nothing I can suggest to you. You should be able to recognise which one.
