So how does this card work. Because I seem not to understand the second line on the card; ''During your Battle Phase, if you control an Ultimate Tyranno that can attack, monsters other than Ultimate Tyranno cannot attack. Now I had Cyberdark Dragon (equipped with a monster) and a facedown cyberdark keel and Hassleberry had Ultimate Tyranno and Tyranno Infinity (with 2000attack). First he attacked my cyberdark dragon with his ultimate tyranno (so my equiped monster goes to the graveyard, while cyberdark dragon self survives), then he attacks my cyberdark keel with his ultimate tyranno. Okay I understand so far. Then he attacks my cyberdark dragon with his Tyranno Infinity... HOW??? How am I suppose to read Ultimate Tyranno's effect of '' monsters other than Ultimate Tyranno cannot attack.'' ?????
You misread Ultimate Tyranno. It only prevents its controllar's other monsters from attacking if Ultimate Tyranno is capable of attacking. Once it's attacked all of your monsters, they're free to attack with whatever they want.
aah. Okay, so basically, that is not a drawback. It just states that you first have to attack everything with ultimate Tyranno, before unleashing your other monsters. At least your explanation is much better/clearer than the cards text. Thanks!
There's a difference between misreading the card and the card just having a poorly worded effect. The first erratum makes more sense than the second. This is unreasonably unclear even if you very carefully read the card.
