TrickBot, Tricky Bot

When TrickBot, Tricky Bot enters the battlefield, trick target opponent. (Draw
cards until you have two or more cards in hand, then target opponent looks at your hand. Choose
a card from your hand in secret and exile it face down. That opponent names a card, then you
turn the exiled card face up. If they did not name
the exiled card, you may cast it without paying
its mana cost.)
