>>53223684Do you mean like Weak Armor, or like Power-Up Punch?
Honestly, if you want to nerf Speed Boost I think this suffices:
>The Pokemon raises its Speed every time it does damage with an attack.Gets rid of the synergy with Protect and Substitute that makes it so powerful and linear, and instead rewards you for taking risks and finding moments to click an attack. Also forces you to pick between boosting your other stats and boosting your Speed, unless you want to throw out something like Power-Up Punch. I don't even think multi-hit moves are a problem, if you're willing to spend a moveslot and a turn using Pin Missile then I think you're entitled to your huge speed boost, godspeed.
