Hey, good points! Anyways, I never run bulk investment on it unless I specifically use the SpD set, which I still believe is mediocre in this metagame and should not be used (I'll get to that). It needs the speed and attack to pose an adequate threat against many of the mons found on offense. In particular, Zygarde and Kyurem-Black hate taking Dragon Claws, and Zard X provides something valuable to its team by being able to take care of those two. If Fini handles them well enough you could even drop Dragon Claw and go for something else like maybe DD instead.Well, Zapdos is a Fini switch in so with the Misty Terrain now Zard X cannot be Discharge paralyzed. Though Dragon Claw getting weaker sux, do not forget that it only applies to targets on the ground. Damage against Landorus-T, Lati, Zapdos is still the same and I feel like people forget about this. Still annoying against mons you would like to use Dragon Claw against like Zygarde and Kyurem-B, but the core itself sounds pretty good overall.
Do you guys use any bulkinvestment on 3 Atks Roost Zard X or just max Speed max Atk Jolly? I think you need that 328 Speed 100% and Roost should be enough for longevity.
I honestly can't see bulky Zard X being very good in this meta. As it is, Zard X isn't all that great. It's weak to Rock and Ground, its speed tier isn't really fantastic and it has 4MSS. I don't see bulky Zard X doing well when all 3 of those types are running more and more rampant in this metagame. Diancie-Mega and Ttar both just got much better with the Dugtrio ban - which in itself helped bulky Zard X a lot - and do way too much to it. The 100 Speed Tier is very important for Zard X as otherwise many mons like Zygarde and Kyurem-Black can outspeed and just straight-up kill it. I definitely wouldn't slash Wisp at all and just unslash SD, because it really needs it to hold much against many threats that could otherwise switch into it freely. Wisp is what makes it able to function against a lot of the meta. Definitely use wisp in this metagame. That being said, it's not particularly that bad, I could see it working decently well but it's not really optimal.
I'm glad that people are finally beginning to realize that Zard X doesn't have to be a DD sweeper, and is rather bad at being one. It's much better off as a breaker or even as a bulky mon. With this I hope that people develop it more and maybe it'll get a better standing in the meta.
So much for my dreams of sweeping uu with it... maybe next gen...
