Mow down almost any monster then attack directly for heavy damage! Since it only destroys the monster with the highest ATK as opposed to just any monster, its rating is 3/5. It's not that great a card since you need Dark Magician out to use it but it can be okay if it destroys your opponent's only monster but still not to impressive from a playability standpoint. What hurts it is the fact that not many of the decent Spell Cards out there are run in more than 1's, leaving this card with not much to take out. The key phrase is "while you control a monster(s)". That phrase alone brings down this card's playability as it has only uses for monsters that cannot be destroyed by battle and there aren't many.

If you have DH - Defenders out, this card is okay but not much else beyond that.  Useful for bringing out monsters like Light and Darkness Dragon or Despair from the Dark but its stats are low and it has no protective effect. With stats of just (300/100), you'll want send her to the Graveyard since it will keep the damage low (unless you have no other monsters out) and it can be okay for searching out Crystal Beast Amethyst Cat but that's about it. Another card from CP05 with limited uses and low stats.

This card isn't very devastating unless you combine it with CCV and EEV and the activation requirement of a 2000 ATK or higher DARK monster hurts it even more. Not much going for this card. For one thing, it only works on Effect Monsters whose effect activates upon summoning it, unless your opponent controls no monsters and you won't want to use it on your only monster. The only use for this card is to buy time to get a decent monster out and even then, it's not worth it since it applies to you as well, meaning you won't likely have anything to use for protecting your monsters. This card's level may be 4 but its rating is only 1 and with good reason as it has absolutely no playability whatsoever.

About the only use is to annoy your opponent for making them toss out one of their best monsters but you have to wait until the opponent has at least 4 cards and even then a monster isn't guaranteed. While stats of (2200/2800) may not seem that impressive, it makes him easily destroyed so you can take your opponent's best monster and use it against them! Plus Foolish Burial makes him easier to summon! The only reason I rate this guy a 2/5 is because you can take out any card your opponent controls and with Second Coin Toss, your chances of success got easier but he's no match for even Tri-Horned Dragon. Run over Man-Eater Bug, Magician of Faith, Morphing Jar, and even Sangan with this guy out without having to worry about their effects but he can't be Special Summoned from the Graveyard. A great card nevertheless!

A decent card! Not only does your opponent take all Battle Damage if the token is attacked but you can tribute it! Since you must pay to keep the token out and you can't attack with it, this card's rating is 3/5. With such low stats, there is little that this card can be useful for. Keep this card in Kaiba decks unless you're using him for one of the more decent ways. There's nothing magical about this guy unless he magically makes your deck disappear with his effect. Overall a horrible card to use. While it can deal massive amounts of damage, it has to stay on the field, leaving it wide open to MST, Heavy Storm and others. If lucky, it can win you duels but luck doesn't happen often.
