I meant that it is HARD trying to competitevly train a Pokemon.
Anyway, let's say this:
I am prepping for a tournament. Because EV/IV training is so tough, I do not go to the BF or Poketopia, so my Electrivire is EQ-less.
Fast forward. Final match of the tournament, my perfectly EV trained, Adamant, max IVs Electrivire against the opponent's Electrivire who is trained casually, but has EQ.
I use Fire Punch, because I know none of my other moves will do much besides Brick Break and Ice Punch, and I want to burn the opponent. However, the opponent does not faint, or is burned.
The opponent uses EQ. It has enough of an attack stat to OHKO me.
Game over. I lost because I did not clone that TM Earthquake in Emerald, and instead kept it there to allow a Salamence to learn Earthquake and sweep the BF.
