"Trap jammer" does not work during battle phase.

[Epims]

Hello, the card "trap jammer" does not work during battle phase against the "Mirror wall" or "Metalmorph".

One of two possible answers:

1. did you set the activation key to off or on?

2. Was Mirror Wall/Metalmorph actovated before the battle phase? If so trap jammer cannot go off because both cards were already activated.

Or you tried to use it the turn you set it.

Hello, Thank you for your help. If I remember correctly, in all cases the opponent's trap cards were placed face down on the field. I put the "Trap jammer" card face down on the field during Main phase then I launched the attack (= Battle phase) and the opponent triggered his trap and for my part I could not activate my "Trap jammer" card. I have the same case in others duels and there was no monster or anything that prevented me from triggering my "Trap jammer" card.

This here is the problem. You cannot activate trap cards on the same turn you set them on the field.

I understand now... Thank you. (Thread closed)

Trap Jammer needs buff. To be reworked as quick play trap, this way people would actually use this card, and it will work well in this meta.

Where to begin...

Cards in YGO either get limited, banned or errata'd to be less potent. "Buffs" aren't applicable here. There aren't any quick-play traps, only counter traps that have higher Spell Speed. Anyway, Trap stun is already a thing, as is Dark Bribe.
