Electivire-Mega
Ability: Motor Drive ----> Contrary
Typing: Electric / Fighting
Stats:
HP: 75 ----> 75
Attack: 123 ----> 153
Defense: 67 ----> 67
Special Attack: 95 ----> 125
Special Defense: 85 ----> 115
Speed: 95 ----> 105
Base Stat Total: 540 ----> 640
Movepool Additions: None
Description: However Contrary is higher than Electivire's ability restriction, I think you'll find it is balanced given that the only stat Electivire can boost independently is its speed, via it's new STAB, Hammer Arm. Also however 153/125 offences may appear scary, you'll actually find that without Life Orb Mega Electivire is actually weaker both physically and specially. Though STAB Hammer Arm from Electivire-Mega hits exactly as hard as LO Electivire's Wild Charge. What makes Mega Electivire really strong is its ability to clean upon acquiring a Speed Boost from Contrary Hammer Arm, being far more efficient then Motor Drive and quickly boosting out of control to unmatched pace. Also having vastly superior coverage thanks to its new Fighting STAB is greatly appreciated. Do also note Contrary's ability to ward away intimidate users, allowing Electivire to punish threats like Landorus-T, killing it with Ice Punch and proceeding to clean. What's also cool is that the unique Electric / Fighting typing gives a great match up vs other prominent threats like Bisharp. What holds Electivire back the most is its still extremely flimsy Defence, meaning you are wiped out by any stray Earthquake coverage from pokemon you can't OHKO, and it's dual STAB and 105 means that Scarf Latios has no problem coming in and OHKOing you with Psyshock even after a Speed Boost from Hammer Arm. Strong priority can also be a problem, especially if you're forced to use Wild Charge a couple times as the recoil stacks up pretty hard. Status ruins you too. But overall still an extremely reliable cleaner that has the potential to be extremely threatening.
Magmortar-Mega
Ability: Flame Body ----> Mega Launcher
Typing: Fire / Steel
Stats:
HP: 75 ----> 75
Attack: 95 ----> 95
Defense: 67 ----> 117
Special Attack: 125 ----> 175
Special Defense: 95 ----> 115
Speed: 83 ----> 63
Base Stat Total: 540 ----> 640
Movepool Additions: Aura Sphere, Flash Cannon
Description: Again, 175 SpA, seems like a lot. 125 + Life Orb actually hits harder. What Mega Magmortar has going for it is unresisted coverage between STAB Fire Blast & Flash Cannon, Pseudo-STAB Aura Sphere, and Thunderbolt, coupled with the typing and bulk to allow you to use it effectively. Mega Magmortar is capable of utilising its plethora of 4x resists to invalidate certain attackers, and then absolutely punish the hell out of possible switch ins. Taking on many top threats such as Latios, Clefable, and Mega Scizor etc. Mega Magmortar also has some useful utility options such as Clear Smog and Will-O-Wisp, coupled with its ability to absorb opposing Will-O-Wisp and Toxic. Magmortar does run the risk of getting worn down though with no recovery or Leftovers, and an SR weakness pre-mega. Mega Magmortar could also be a notable mon to have around on a Trick Room team, with its particularly handy ability to tank Talonflame's Brave Bird with ease and remove the bird with Thunderbolt.
Tangrowth-Mega
Ability: Regenerator ----> Heat Proof
Typing: Grass
Stats:
HP: 100 ----> 100
Attack: 100 ----> 110
Defense: 125 ----> 135
Special Attack: 110 ----> 140
Special Defense: 50 ----> 100
Speed: 50 ----> 50
Base Stat Total: 535 ----> 535
Movepool Additions: Clear Smog
Description: With Tangrowth's new found 100/100 Special Defence, the mon no longer finds itself reliant on AV and Regenerator to take on special attackers. This means that now all of Tangrowth's sets are able to run different means of recovery such as Synthesis, Leech Seed, and Giga Drain now off of a respectable 140 SpA. This gives Tangrowth a much more prominent field presence as it it isn't forced out so easily, which is pushed even further by the addition of Clear Smog, crushing the ability for the opposition to try set up and boost past your bulk. Mega Tangrowth's new Heat Proof ability is extremely useful now allowing you to take Fire types moves neutrally, avoiding the 2HKO from Mixtini's V-Create. Heat Proof also halves Burn damage, so you can out heal burns with Leech Seed. Over all this makes Tangrowth an extremely versatile tank and pivot capable of checking a plethora of threats, and having solid offences with great coverage to pick and choose what you can remove in order to best support your team.
