This is bullshit,I was at the final battle against N in Black version and I swapped out my Basculin for the Zekrom I had just caught.I did this because I wanted a little more bulk on the team.However,I didn't know that if you choose to add the Zekrom it replaces the pokemon in the lead
spot.It ruined everything,I had my strategy ready to go with my eviolite Boldore as my lead.But as the battle started the game put Zekrom up against N's Reshiram.I panicked and switched to my specially defensive Cofagrigus.I got hit with a Fusion Flare and it did around 35%.I made up my mind and proceeded to click disable so that I could have a chance to resto-chesto up to full but I get hit with a critical and it was all over from there.I sent in my original lead,Boldore,fired off a few rock blasts but got 2 hits both times and that allowed him to full restore.
I was so fucking pissed I soft reset my DS and deleted the save file after taking one last look at my team.I'm sorry bros,I never should have replaced Basculine.
