Actually, both substitues were exactly the same size (10%) (which was also the maximum I put into the randomizer each time... strange). However, Sandshrew got a bit luckier with the Slash damage, since he did over 10% with the first hit, but Mercury only did 9%. And the sub shouldn't be in the final stats... I thought I had already gotten rid of it =/ *edits*

For Toxic, I have it do 1% or 2% damage each turn, depending on how much poison actually hits. It will very slowly get stronger (maybe in three rounds it will be 2% or 3% instead of 1% or 2%)
