Great game LinIsKorean, the tension was really thick for me waiting to find out if I hit myself or not.
I used:
Blissey - Heart Mail (Earlier in the tournament was a chople berry)
Bold - Natural Cure - 252 HP / 252 Def / 4 Spe
Toxic
Counter
Rest (Earlier in tournament was Softboiled)
Protect (Earlier in tournament was Seismic Toss)
This was an anti-typical strategies Blissey, with Mail to stop people from Tricking, Rest to stop toxic stall, Protect to scout, Counter for physical pokemon, and Toxic for special pokemon. After careful examination I decided that Mail, Rest, and Protect were more important then their replacements, as Chople just beats Infernape, a pokemon that I didn't expect to see much of with focus sash banned. Although I was a little worried about losing the instant recovery of softboiled, not losing to toxic ended up out weighing it's use in my opinion. And after a scare about mispredicting a mixed pokemon, I decided to use Protect instead of seismic toss, as I didn't expect to see many special steels or poison pokes in the tournament.
