Mental Seeker...doesn't this guy look like someone out of the Mega Man universe?  We have a Level 3, Earth attributed, Psychic-type Tuner monster, with 800 attack and 600 defense.  So, I really like the effect of this card, but I hate what you have to do in order to be able to get it.  When this card is Special Summoned from being removed from play, your opponent reveals their top 3 cards of their Deck to you.  One of the cards, of your choice, is removed from play, while the other two return to their Deck, and are shuffled.  Obviously this guy combos well with yesterday's card, but I still prefer Psychics before they started all this removal stuff.  You might even have to remove this card yourself, just to pull it off.  Not bad, but kinda tricky.

You'll probably never end up summoning Mental Seeker over Esper Girl--while Esper draws a card, Seeker provides some intangible advantage by eliminating an opponent's key card... if you're lucky. And if you find any Limited cards, you'll know they aren't lurking around anywhere. Actually, that doesn't seem too much worse than a draw.

What sets the Seeker apart is that it's a level 3 Tuner. This stacks up to bigger Synchros, whether through other Synchros or not. Jeez, try typing Seeker and Psychic and Synchro together. It's very difficult.

You can quickly hop to Lifetrancer to remove more Psychics and summon them back through Brain Hazard--Esper turns Lifetrancer into Hyper Psychic Blaster, and Seeker works off of Nightmare. Very good psynergy there (a corny pun AND a Golden Sun reference! I win!)

3.8/5
Art: So is he a little kid, or...?
Fun Fact: I absolutely refuse to use Sveta.
Tomorrow: Hush! Don't even talk about Sveta.

Mental Seeker reminds me of a Hero Kid in appearance. Unlike the Hero Kids he is not utterly useless. Three star psychic type tuner with forgetable stats; 800 atk /600 def. When Mental Seeker is SS from the removed zone reveal the top three cards of your opponents deck, select one and remove it from play, then return the rest to the opponents deck. One can really take advantage of this little guys effect with Serene - card reviewed yesterday- as she pitchs a psychic to the removed zone via her effect. Same can be said for Silent Psychic Wizard and Hushed Psychic cleric. You can also bring Mental Seeker out via Overdrive Teleporter, Overmind Archfiend, or Emergency Teleport. With Mind Seeker and the remaining psychics from this set those interested in building a psychic deck now have some decent choices. As I mentioned yesterday the deck can be very frustrating to play against and has much OTK potential. So try them out if you are bored as you now have much at your disposal to play around with.
