Oooh...another thought occurs. Responding to PokePop's reply here: And correlating/contrasting with the Extra Smoke ruling: Extra Smoke is applied before W/R, hence the effect is on the attacker. Close Combat is applied after W/R, hence the effect is on Lucario. So, extrapolating from that: Effects applied before Weakness/Resistance are placed on the opposing Pokemon. Effects applied after Weakness/Resistance are placed on the Pokemon invoking the effect. Is this a good meta-rule to keep in mind? Or are these things mostly on a case-by-case basis?
