You can only activate 1 card with this card’s name per turn.
(1): If your LP is lower than your opponent’s, and your opponent controls a monster that has the highest ATK on the field (even if it’s tied): For the rest of this turn after this card resolves, you cannot Set Spell/Trap Cards and you can only activate a card/effect one time, also reveal 3 cards with different names from your Deck, and if you do, shuffle them and return them to the top of your Deck, then draw 1 card.
