*bumping this thread*
Regarding Blaziken-Mega: It actually used to be
D Rank in the first iteration of this ranking, but we decided to remove it because it is largely outclassed by Groudon-Primal. The only thing going for it is the STAB in Superpower, which really isn't that great when you consider that Groudon has basically everything else better, including massive bulk, better dual STAB (Fire / Ground is unresisted), and arguably better defensive typing. Basically, you're losing out on a ton of bulk just for the ability to get STAB on fighting, which isn't really that relevant as you'll probably be spamming V-Create most of the time anyways.
Some other things I'd like to bring up for discussion:
At the time it was originally ranked, Hoopa-U was placed very tentatively at
C+ because it was fairly new and had not been tested very much. How has it fared so in the current meta? Is it able to properly take advantage of its massive attacking stats and unique signature move, or is its low speed and frail bulk too much of a hindrance to effectively use it?
It was recently brought to my attention in the BH CCaT thread that Ho-oh is largely outclassed by Groudon-Primal, especially in offensive roles. Does it have a strong enough niche to stay in
C Rank or should it be moved down? The main niche it has a unique defensive typing and much more special bulk than Groudon. However, its typing also means that it is hugely hindered by rocks if it does not use Magic Guard as its ability, and using Magic Guard can take away potential utility in other abilities.
I think we've all agreed that this powerhouse by no means should remain in
D Rank, but we haven't yet reached a consensus on exactly where to place it. To summarize our previous discussion, Deoxys-A has the potential to deal massive damage with its insanely high attacking stats and base speed. It also has the unique niche of being able to kill Imposter Chansey due to its sheer lack of any bulk at all. However, all of this hinges on keeping Deoxys-A at full HP so that its Focus Sash stays intact, which requires a great amount of team support.
