Hmmmm best u say. Mischure costs 1 card this card costs 2 cards. Champions vigilance costs 1 card this costs 2 cards. Order2charge costs 1 card and 1 guy who would die anyway. This card costs 2 cards
michizure and otc both require you to have a monster already on the field, and vigilance is no where near splashable. not saying this is strictly better than otc since it's not quickplay but being able to discard anything from your hand is a big difference
michizure costs 1 card?? why?? you need michizure and a destroyed monster, but with this you only need tribute to the doomed and any card in your hand so it is arguably better than michizure and much more versatile... and CV is situational
