its a horn target so it must be a good card

You might want to re-word the 1st effect to just say Trap Card, instead of Continuous, and then the 2nd effect should be 'If this card is Equipped with a Trap Card', rather then 'When this card is affected by a Continuous Trap'.

piercing isn't anything new, and 1800 atk is meh for the atk amount

the destroying 1 card on the field is good but it's a bit too situational

I would have allowed this for spells as well, not traps only

similarly for the piercing effect I don't see why you allowed only equip traps
