I don't know if you saw my comments, but I am really excited to do this rate. I have had a lot of similar ideas in the past, and it'll be awesome to show you how I think you could best combine them. I used a Mega-Houndoom team in a tournament a few weeks ago, and I'd really like to share that team with you because I think you could pull ideas from it, and really form your own take on the team.
The Rate (changes will be in bold)
Houndoom-Mega @ Houndoominite
Ability: Flash Fire
Level: 50
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Heat Wave
- Dark Pulse
- Solar Beam
- Protect
This looks good. Just make sure to use timid. Houndooms biggest asset over Zard-Y is his speed, make sure to take advantage of it.
Whimsicott @ Focus Sash
Ability: Prankster
Level: 50
EVs: 252 HP / 4 Def / 252 Spe
Timid Nature
IVs: 0 Atk
- Beat up
- Tailwind
- Taunt
- Sunny Day
I added the tech of Beat up onto this whimiscott, it will be more obvious why later. I wouldn't worry about not having an attacking move. Even with Moonblast it isn't doing much damage, and Whim is faster than most Taunt user, so you have to taunt them first. Rest of set is explanatory.
Lucario @ Lucarionite
Ability: Justified --> Adaptability
Level: 50
EVs: 12 HP / 252 Atk / 244 Spe
Adamant Nature
- Bullet Punch
- Drain Punch
- Blaze Kick
- Protect
This the big change on the team. Practically no one knows that Lucario's hidden ability is Justified (same as Terrakion) this can raise his attack 4 stages before he goes mega. Once he is mega, Bullet Punch is base power 80 (because of Adaptability) and has priority. Drain Punch has 150 base power and provides healing. Blaze Kick is coverage, and can be powered up by a Sunny Day. Protect is obvious.
This was the key change to the core I was talking about earlier. Lucario and Houndoom compliment each other well. When people see Houndoom, they'll expect the Mega form, so you can catch them by surprise with the Mega-Lucario. You can surprise people 2 fold when you use the never seen justified form.
Aegislash @ Ghostium Z
Ability: Stance Change
Level: 50
EVs: 188 HP / 252 Spa / 68 Spe
Mild Nature
IVs: 0 Atk
- Shadow Ball
- Flash Cannon
- Shadow Sneak
- Kings Shield
Fairly standard Aegislash. Is your new z-move user, and a good replacement for Umbreon. Its an excellent pivot between defense and offense with its two different stances. This is a relatively fast Aegislash to beat other Aegislash, Cresselia, and Gothitelle- as well as taking advantage of a tailwind more. I also opted for Shadow Sneak as a stealthly option to pick up surprise KOs.
Tapu Fini @ Mago Berry
Ability: Misty Surge
Level: 50
EVs: 236 HP / 148 Def / 76 Spa/ 4 Spd/ 44 Spe
Calm Nature
- Muddy Water
- Moonblast
- Calm Mind
- Protect
Your new Tapu, which allows you to get control of terrain war. This is a calm mind set, so if Fini is in a situation where neither Pokemon can do a lot of damage, or if you predict a switch/protect, Calm Minding can really put yourself in a pretty optimal situation for the rest of the game. Muddy Water and Moonblast are standard. EV spread and the pinch berry for Longevity. I think Fini is a better fit on the team, but if you wanted to sub in Feraligatr it could probably work (just wouldn't run as smoothly).
Hydreigon @ Choice Specs
Ability: Levitate
Level: 50
EVs: 60 HP / 180 Def / 132 SpA / 4 SpD / 132 Spe
Modest Nature
IVs: 0 Atk
- Earth Power
- Dark Pulse
- Heat Wave
- Draco Meteor
The new dragon on the team. A bulky Hydreigon set with specs is the optimal set to take advantage of Tailwind. Move set is fairly standard except I opt for Heat Wave over Flamethrower for the spread damage that can be powered up in the sun.
I hope you like the new team, and I really hope that the major changes are okay with you. I just saw a lot of potential with the team, and I really wanted to optimize the battling strategy to its strengths.
Let me know how you feel and if there is anything else you want suggestions on. Thanks!
