If you're playing GBs, than it is normal for you to have more spells and traps than monsters, because GBs need alot of protection and can tag out for what monster you need at the right time. There is no real ratio of how many of each card you should use, it all depends on what deck you are playing and what works for you. Why don't you post your deck list of your GB deck and we can look at it and if you would like any suggestions ^_^
