There is no way to have a monster with an ATK above 1000 attack directly using the effect of “Secret Pass to the Treasures”. When you target a monster with “Secret Pass to the Treasures”, and the monster’s ATK is increased above 1000 afterwards, the monster cannot attack your opponent’s Life Points directly.
If the monster attacks your opponent’s Life Points directly, you cannot use an effect such as “Rush Recklessly” to increase its ATK above 1000 during the attack. If a monster attacks directly using the effect of “Secret Pass to the Treasures”, “automatic” increases will not apply (“Super Robolady”, etc.). If you use “Secret Pass to the Treasures” on “Injection Fairy Lily”, and attack directly, you cannot activate the effect of “Injection Fairy Lily”.
You cannot activate “Secret Pass to the Treasures” during Main Phase 2 or on the very first turn.
This card targets a monster.
Netrep Rulings:
Monsters able to attack more than once in a turn may attack directly each time from the effect of “Secret Pass to the Treasures” as long as the ATK of the monster does not rise above 1000.
