I am relatively new to yugioh so I wouldn't know too much but wouldn't this leave a possibility of bricking just with handtraps so in your turn you may be left with no plays?
Bricking is always a possibility. But with as many one card starters as the deck has its over an 85% chance that you see one. And on the very miniscule chance that you open just handtraps, your opponent likely won't be playing much, and your chance of seeing one of said starters as your draw is high.
