Shadowverse

Well, if you have health reserves and control in hand, this card is practically a guaranteed win; it's very difficult to clear more than two snakes in one turn. But, of course, this card was stronger before, when it was guaranteed to be available on the fifth (or so) turn; now it's situational, you need to survive and have a tempo advantage. However, since I'm not a fan of the Blood faction, this perspective might be inaccurate.
