Cyber Shadow Gardna question

this is the eff:
Activate only during your opponent's Main Phase. After activation, Special Summon this card; it is treated as an Effect Monster Card (Machine-Type/EARTH/Level 4/ATK ?/DEF ?). (This card is still treated as a Trap Card.) If this card is selected as an attack target, the ATK and DEF of this card become the ATK and DEF of the attacking monster. This card is Set in its Spell & Trap Card Zone during your opponent's End Phase.

when my opp atacks it those the trap go to grave or to s/t zone?(s-spell t-trap)

if your opponent attacks Cyber shadow gardna the monster its sent to the graveyard as a result of battle its not set down again except if your opponent didn't attack it.

ok thx for the answer i'll lock this
