Ludicolo just defeat alone my pokemons I even used ice or fire moves or flying ect. due to its weakness, but it was faster stronger and undestroyable, so I want made my team strong like others can do. I don't know if it's normal but I used 2 dragon dance, next mega evolve gyarados and use ice fang..this work on grass part like a fart
It sounds to me that your Pokemon's training isn't the problem, it's your lack of knowledge. As previously stated, Ludicolo is neutral to Ice and Ice Fang has low base power, so it's not like you should expect massive amounts of damage it. If a mediocre pokemon like Ludicolo is beating you, then it's pretty indicative that your team has some weaknesses and/or you lack skill (prediction, strategy, decision making in general).
What you said about Gyarados is very interesting, though, and I can think of several reasons that could explain your issue. Despite Ice Fang only being neutrally effective and having low power, I doubt that a +2 Mega Gyarados would do little damage to it without something else being the problem. Are you sure there weren't other stat boots involved, such as the Ludicolo having Defense boosts(maybe by Baton Pass?), or Gyarados having its Attack lowered (maybe by Intimidate?)? Had your Gyarados been weakened before sending it in? Maybe your Gyarados has poor Attack IVs and a bad nature, neither of which you can change after a Pokemon is caught, so for example a Timid 0 Attack IV Gyarados always going to be worse than say an Adamant natured Gyarados with 31 Attack IVs and there is no way to fix this without getting another one. Your questions regarding EV training, and not even knowing that super training is EV training makes me think that you also just EV trained wrong, too.
However, the
biggest problem is that you made some bad decisions in battle and these mistakes cost you a match you could have and should have won. You should
not have mega-evolved Gyarados. Regular Gyarados is Water/Flying and therefore neutral to Grass moves. Ludicolo is part Grass and therefore gets Same-Type-Attack_Bonus on Grass moves. Mega evolving Gyarados gets rid of your neutrality to Grass moves and instead makes you weak to Grass moves. Now that Gyarados is Water/Dark, Giga Drain or Energy Ball or whatever Ludicolo has is now Super Effective instead of neutral. This was clearly a bad move. If you hadn't just mega-evolved without thoroughly considering the consequences, your Gyarados would've lived longer, and would have been able to Dragon Dance more KO the Ludicolo.
