Urth, Purifying Elemental. Enough said. But for those who dont know what this is, lets say he is the savior of yellow. Yellow is full of quick casted creatures which are usually blockers, and spells that tap your opponents various creatures. Yellow has been about speed and the spells that go "tap" in the night, but now they have a fattie. Urth is a double breaker, 6 mana for 6000 power. Now that alone is a threat. But that other little text underneath the double breaker gives Urth its Umph. "At the end of each or your turns, you may untap this creature." WOW. That is incredible. This gives Urth the ability to smack your oppenent or thier creature, and then have him come back and be invulnerable to attack from an untapped creature. Many creatures, especially fire type creatures have power attacker ability which will easily boost their power high enough to slay Urth, only if he is tapped, but wait... He shant be tapped. Now you more experienced players are thinking well now hes suseptable to Death Smoke and Gatling Skyterror. Well yes and no. If you know your oppenent is running Darkness cards, then u know hes running Death Smoke, and leave him untapped if he cant be killed. Its all on how you play your cards. But Having a yellow deck with 4 Urth's in it can make anyone a lot nervous. Happy Playing.
