I'd like to Nominate Mega Houndoom and Durant in these rankings, in which I'll state their places after my explanation of their capabilities.
Facing competition from a more common mega called Charizard-Y, what does Mega Houndoom have to bring to the table? 2 things:
I: Much more power at its disposal, along with an actual boosting move to take advantage of it.
II: A higher speed tier, matching up to very important pokemon.
I: More Power
- Mega Houndoom's ability Solar power allows its stab Fire blast and dark pulse to reach to power levels that rival Reshiram's expertise in Ubers, allowing it to at least 2hko pokemon that its competition, Charizard-Y, cannot. 3.375 stab Fire blasts (sun+solar power+ stab) hurt a butt-ton, in which resists to the Fire Dark stab combo don't even matter anymore. Watch as specially defensive mons like Blissey are no match for the powerful hound from Hades himself!
252 SpA Solar Power Mega Houndoom Fire Blast vs. 252 HP / 4 SpD Blissey in Sun: 328-387 (45.9 - 54.2%) -- 96.1% chance to 2HKO after Stealth Rock and Leftovers recovery
That is impressive, which makes Mega Houndoom fulfill the role of a great wallbreaker that isn't to be messed with, whereas in the case of charizard-y, its more likely that mons like blissey and sylveon are able to stall him out through recovery and toxic stalling, etc. Having the chance to avoid all that with Mega Houndoom makes it a pretty good choice for a mega slot. Even better it gets Nasty Plot, allowing it to wallbreak with more Power at its disposal. After a Nasty Plot in the sun, spdef tran gets 2hkoed with a minmum of 74%.
II: Higher Speed
- Mega Houndoom reaches a speed tier of base 115, allowing it to outspeed very important mons such as the lati twins, gengar, mega lucario, and speed tying with azelf and starmie, in which he can obliterate with its fire and dark stab respectively. Outspeeding the musketeers from last gen also helps, as well as mega pinsir, the incarnate forms of the genies, garchomp, etc.
Despite all these good attributes, there is a reason why mega charizard Y is preferred. Much more durability with roost and a good specially defensive stat of 115, as well as a decent fire/flying typing, mega charizard Y is able to last longer, while Mega Houndoom is put on a timer with the solar power side effect as well as taking a turn for another mon to set up sun for him. With all this taking into consideration, I consider Mega Houndoom a B-/B ranking.
Durant: Facing competition from scizor and genesect, what does durant bring to the table?
I: Higher speed
II: Immediate Power
III: Best physical coverage out of all the bug/steels.
I: Higher speed
- Durant sits at a base speed of 109, outspeeding a lot of key mons, especially the majority of fire types up to infernape, as well as the musketeers, chomp, etc. Being able to outspeed them is a godsend, because it can't be checked by any of these mons without taking huge damage first thanks to its immediate power and physical coverage.
II: Immediate Power
- Durant's hustle ability is basically a free choice band with the ability to switch your moves; top it off with a life orb, and you can do more damage than an adamant scizor or escavlier. Take this into account:
252 Atk Life Orb Hustle Durant Iron Head vs. 252 HP / 0 Def Togekiss: 471-556 (125.9 - 148.6%) -- guaranteed OHKO
In comparison: 252+ Atk Choice Band Scizor Iron Head vs. 252 HP / 0 Def Togekiss: 450-530 (120.3 - 141.7%) -- guaranteed OHKO
See? Scizor has to have a choice band and an adamant nature in order to even come close to durant's damage output, whereas durant doesn't have to, which greatly improves durant's wallbreaking capabilities. Even better, durant gets hone claws to fix that accuracy side effect of hustle, making it hit even harder with no drawbacks. It even 2hkos skarmory and hippowdon after a boost.
III: Best physical coverage out of all the bug/steels
- Let me give you a list of durant's coverage moves: iron head, crunch, x-scissor, thunder fang, stone edge/rock slide, and superpower.
- compare that to scizor's: bug bite/u-turn, iron head/bullet punch, knock off, acrobatics, superpower.
- and genesect's: u-turn/x-scissor, iron head, blaze kick, extremespeed.
- and escavilier's: megahorn, iron head, drill run, knock off, double edge.
Durant hits more supereffective coverage on the physical side in comparison to all the other bug/steels, hitting bulky waters like gyarados, every fire type in existence, mandibuzz and other flying types, as well as bulky ghosts and psychics, ferrothorn, skarmory and more.
It has some drawbacks however, its the most frail out of all the bug/steels, especially with a 44 spdef stat, meaning its very hard to find an oppurtunity to boost. priority is everywhere, and Lando-t (defensive) is a menace to it. With all this in consideration, I propose a C+/B- range.
