It´s not that the batlle phase doesn´t exist it´s that by the time you get to battle phase your opponent already wiped your field and you couldn´t do anything to stop them bcz you are locked to battle phase only. What´s the strongest backrow this card can counter? wall of disruption and even there it´s pointless since SHS attack in defense position.
In term of real trap, it should be drowning mirror force, doesn't target/destroy but this card supposed to counter handtraps than real trap nowadays like kiteroid, the kuribohs, temperance, bb veil, score, etc
In my opinion, it’s worth playing over soulshield wall. Sure you lose 200 points and can’t do the otk, but a niche effect that occasionally sees use is better than an effect that will never see use.
