I'm such a newb, what's the difference between Blind and Draft pick?
You can see what champs the enemy is picking and you take it in turns to pick.
It goes banning phase, picking phase then free phase. Banning phase Blue bans a champ, then purple bans one, then blue, then purple, then blue ,then purple. So a total of 6 Banned champs. These bans apply to both teams so if you ban someone you can't use them yourself. After this blue picks one champion, then purple picks one, then blue picks one, then purple picks two, then blue picks two, then purple picks one, blue picks one, purple picks one. Draft mode also makes it so if the enemy has picked a champ you can't pick that champ. That champ becomes exclusive to that team.
