Note that all my movesets are smogon ones, and the reason behind them is pretty much what is stated on the site. However, I do try to say at least a little about them.
(Edited)Intro: After the suggestions you can read on the thread, I made some changes to my team, and came up with the one you see here now. Replaced Toxicroak and Chansey with Celebi and Landorus, changed a move on Rotom and the item on Heatran. The team now is faster, with greater coverage and more power, with one helping each other (at least from the most part as I see). I tested every single suggestion on this thread and did so from yesterday up to this edit, which I made only when I felt that myself alone was not enough anymore to improve, and I hope you guys share your thoughts about all that is below.
Rotom-W @ Leftovers Trait: Levitate
EVs: 112 HP / 252 SAtk / 144 Spd
Modest Nature (+SAtk, -Atk)
- Thunderbolt
- Hydro Pump
- Will-O-Wisp
- Pain Split
My starter for most ocasions as will-o-wisp is generally a good and safe first move for the match. Volt switch to scout or deal damage, hydro pump to heavily damage the starters weak against it while they set up. Pain split to regain health and damage some bulky guys. Edit: As suggested, I replaced volt switch with thunderbolt, which has gone magnificently. The power increase has really helped and moreover, I was worried about the lack of scouting, but I didn't miss it at all. This guy has also been showing itself as a very good wall, and outspeeding more than I could imagine.
Celebi @ Life Orb Trait: Natural Cure
EVs: 220 HP / 252 SAtk / 36 Spd
Modest Nature (+SAtk, -Atk)
- Nasty Plot
- Giga Drain
- Hidden Power [Fire]
- Earth Power
Replaced Toxicroak with him, which also helped me a lot. With the given EVs it is even more of a wall than it already is. I tried Ciel's set but in the battles, most of the time they switched out, giving me a free turn to Nasty Plot with this set. Then, almost anything that poped out was sure to receive significant damage in the least, while letting Celebi resist if the attacker is faster in many cases. The 3 attack moves are for covering whatever comes, and I sincerely don't feel more speed is necessary, but I accept criticism, as I am just a newbie out there.
Scizor (F) @ Choice Band
Trait: Technician
EVs: 248 HP / 252 Atk / 8 Spd
Adamant Nature (+Atk, -SAtk)
- Bullet Punch
- U-turn
- Superpower
- Pursuit
Another powerhouse. Bullet punch is great with the priority and even super effective against some stuff. U-turn for scouting, superpower for instant KOs and pursuit to kill those fleeing guys. No edit on this guy, just think I may need to learn how to use him better. Superpower on him, for example, is like the rarest thing I'm ever using on a battle.
Landorus (M) @ Choice Scarf Trait: Sand Force
EVs: 252 Atk / 4 Def / 252 Spd
Naive Nature (+Spd, -SDef)
- Earthquake
- Stone Edge
- U-turn
- Hidden Power [Ice]
The speed problems I've stated on this thread really seemed to vanish with this guy and celebi, as I don't remember what outspeeds it ( and I've been testing since yesterday ). What I see is Landorus needs more skill to play, but with some good advice and practicing I know I can get over this issue. Earthquake just hazards any non-immune pokemon ( in case of resist switch ins ), stone edge and hidden power ice are coverage moves to use along with prediction, while U-turn, obviously, for scouting or killing the ones I can while changing my own pokemon in battle too.
Heatran (F) @ Leftovers
Trait: Flash Fire
EVs: 252 SAtk / 4 SDef / 252 Spd
Timid Nature (+SAtk, -Atk)
- Fire Blast
- Earth Power
- Hidden Power [Ice]
- Stealth Rock
Prefered to let him with more utility than full attack sets. The first 3 moves as brute power against anything weak to them, and those dragon switches, while stealth rock for when they switch but I don't think it's worth using one of the other 3 moves. Sometimes I use him as a starter to put the rocks in the air too. Air balloon to prevent him from dying from earthquake as soon as he pops in the battle. Edit: Again, as suggested, replaced balloon for leftovers, and only in 1 battle ( mirror ) the lack of the former got me. Overall, I didn't miss it, but did not notice any changes with leftovers too, since he is generally instant KO'ed. Also changed nature from Modest to Timid, making him capable of killing other heatrans, in the least ( sorry, don't remember whereelse it was useful, but I know it has been =P ). Suggestions here are REALLY appreciated. If I see any weakness on this one, it would be speed, but I doubt there is anything else to be done about it.
Terrakion @ Choice Band
Trait: Justified
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature (+Spd, -SAtk)
- Close Combat
- Stone Edge
- X-Scissor
- Sacred Sword
This guy.... when I read his description, and I did more than once, I noticed how powerful he is and, for a power-utility team, his stats were needed. Just put him on and damages whatever comes in, sometimes even surprising with a crit from stone edge. His speed also lets me counter pokes that have moves that could kill him, by attacking first with the "best for the moment" move from the list above. Edit: This guy is still a heck of a sweeper! Nothing changed on here, but I noticed it looks like it has more synergy with the changes I've made, but I also guess I'm still not using him to his full potential. Nevertheless, he is still a great adition to my team, outspeeding, walling and surprsing unaware opponents when I can reasonably predict well. A correct X-Scissor can win me a battle.
Overall thoughts: After testing this team like I did, I started to ask myself if there really is anything I can do to improve it or if it comes now to myself using it. I still lose battles and I know there is no perfect team, but any constructive criticism is VERY VERY VERY appreciated. The "perhaps" failures/threats I noticed are psychic ( alakazam ) and gengar, which I've faced very few times, and other celebis, but I think this last one is purely lack of skill from me. Also, I once went against a gallade that gave me trouble. Overall, things like Gliscor, Jellicent and Ferrothorn went from nightmare to "yawn", honestly. Even I did not expect such a thing.
What I feel is most needed now is to improve myself as a player. The Battling 101 #63 did not begin yet and I don't know if I will manage to get a spot on it, but I still want help from good veterans.
Anyhow, constructive comment/rating about anything on this thread is still REALLY appreciated.
Thx in advance
