>>20861560Okay then, let me be more precise here.
You asked if pokemon could ever not be a gamble, I believe it can happen. I tried to give you a quick answer and you swayed it the opposite way because I wasn't specific enough. Let me be more specific now.
New situation, now.
You're playing against stall and you have deosharp. You have rocks and one layer of spikes up. The opponent has four mons left with all of their items on and they're all around ~75% at the most, and you have a Black glasses Bisharp at +2 at 90% health with a life orb. The mons the opponent has are Chansey, Slowbro, Lefties SpDef Heatran and Lefties Clefable.
You lose absolutely nothing by just attacking with Knock Off/Iron Head when Clefable is out. Absolutely no gamble required. When you have a favorable team matchup and have put yourself in a good position. You don't need to gamble.
