In terms of positives, I've seen some bring up the issues of the waifumons being busted, and at first I agreed. However, the more I thought about it and played with them, the more I realized they're only busted when people know how to use them as such. A person with little understanding of Pokemon can't just take these teams and do well with them. They're busted BECAUSE of the proper usage of the tools in their arsenal, and it's really fun making them perform at their maximum potential.
That great to hear. Speaking of which, how exactly do you make the waifus busted? I'm admittedly not a professional pokemon battler(starter glass cannon build most of the time), but I do want your insight into how each one can be made busted. Though before that, I'll give details on how I've kinda learn how to make them busted(or at least ideas).
For Allerita, you simply just need two moves to make her busted. Grande Jeté, and Destabilize. Grande Jete is a steel move that on every hit, raises the defense and special defense. It ain't much, especially against lower level pokemons, but get a tank in front of you, then you can hit it several times for 'free', making your starter pokemon stronger. And once you got some boost to the defensive, that when you use destabilize, which reduce your defensives, to massively increases attack, special attack, and speed. With greater special attack, you can quickly return back to Grande Jete, and start rebuilding your defenses again. Provided that no one got something to withstand being oneshotted(outside of protect), then you can easily wipe out entire trainers with that dirty build. For Eve training, you definitely don't want to waste puting points into attack, all of her most powerful attacks(and Grande Jete) are special attacks. And from what I seen, you can definitely afford to put more points into defense and hp, rather than into the special attack and speed, since those are naturally higher. What items to use, outside of leftovers, I have no idea.
Lopunny is definitely something I haven't used too much, but I do use the extreme speed, sword dance, spin kick, and a physical move that can harm ghost types to do some serious damage. EV training, same for her, except swap special attack for attack. Though I don't know what items to give her.
Gardevoir is unique as a psychic normal pokemon with adaptability. But I assume that giving her Boom Burst and throat spray can make extremely dangerous to face. Add coma which can both deal damage and cause sleep, then you got time to set up calm mind. And shadow ball to deal with the ghost types pokemon. For Ev spread, attack should be ignored, the defense, hp, and speed should get some major investment, and special attack and special defensive should get some evs to make the stats even bigger.
Viruark is definitely a powerful pokemon, though she can be much more useful as a statis inflicter. In fact Caustic Claw and her ability poison touch is perfect for this. She attacks you for large damage, and the enemy rolls 4d20s. If they roll a nat 1, then they either suffer burns, poison, freeze, or paralyzed. Which can be great. Majorly boost her hp and defenses, and moderately boost her attacks and speed, and she could constantly forcing the enemy to roll con saves, simply one shotting them, or getting them to physical attack into Baneful Bunker.
Tsarevniya is unique given her unique ice-grass combo. She got a ability related around getting hit by fire types move, but it doesn't remove her weakness to them. Personally do think that it make sense that fire type moves don't do damage, and instead fuels her defenses, as there are official pokemon abilities that negate fire type attacks. Outside of that, know that she can take serious hits, and with her attack properly boosted, she can return said hits. Do have her running Leaf Blade, Frigid Veil, Tundra Crash, and Frost Flame Blade.
Drakaiden is definitely extremely power, especially when using Hurricane and Thunder in the rain it sets up, not to mention Raijin Breath. You can definitely afford to invest most ev into it's defenses and hp, since both attacks and speed are naturally great. I would definitely think that she would be best a special attack, with Swerving Strike being her only physical move(as it serves as her u-turn)
Vaperon I have nothing since it ain't moded(come back when it evolves further beyond)
Vexinni I haven't messed around with, but do know that it's got a dangerous combo with it's dark type move that forces the opposing enemy to become dark type, then a ghost type attack that deals more damge if the opponent is half-health. And with it's high special attack,Soul Reaper may be capable of pussing the enemy pokemon into the half-range. Especially if it has life-orb. And given it's ability. I doubt life orb can do more damage than it can heal.
Nymphlora is unique, but have figure out that solar flare may be busted, as I'm imagining that it damage all pokemon on the opposite side of the field.
