Select 1 face-down monster you control. Your opponent declares 2 Attributes. Reveal the selected monster. If its Attribute is one of the declared Attributes, your opponent draws 2 cards. If not, you draw 2 cards.
cup of ace is enough, you wont want more than 3 of them, and it's a normal spell so you can use it in the first turn (the more important turn) this trap can be used if you draw a monster and have to wait the next turn to make it useful, better for mill deck
