deck that rely on heavy trap usually dont have OTK potential except shiranui, so take your time, waste all their trap first dont summon your boss monster until you feel safe
Everytime when your opponent sets 3 cards. That will give you a lot of problems. Don't expect them to set useless cards such as Graceful Dice/Spirit Barrier/Metalmorph. People will always set Floodgate/Chain/Karma/WoD. 1 CC in your starting hand can't do anything.
