Sorry I missed last week everyone, I actually took a vacation, which was awesome.  Long story short, my internet access during said time was essentially non-existent.  Tyr of the Nordic Champions opens the week, a Level 4, Light attributed, Warrior type monster, with 2000 attack and defense, which instantly should make you think there is a hinderance with this card, and there is.
 
There is some solid protection for the Nordics in Tyr, as while on the Field, your opponent cannot attack a Nordic monster other than this card itself.  With 2000 attack, that's a decent enough effect.  Now the downside we expected from a Level 4 monster with 2000 attack, if you have no other face-up Nordic monster on the Field, Tyr is destroyed.  Now, I assume this is on either side of the Field, as the card doesn't specify "your side of the Field." 
 
 If you're playing Nordic anything, this actually isn't a bad turn, unless obviously it's something you have in your Hand say first Draw, or when you have no other monsters on the Field.

Today's card is Tyr of the Nordic Champions. He's a 4-star light warrior with 2000 ATK and DEF, which is not shabby considering his level. While he's around, your opponent can't select any other Nordic monsters as attack targets, but if you don't control any other Nordic monsters, he gets destroyed. A somewhat good effect crippled by a bad effect. Nordics have enough support without this guy.

Tyr of the Nordic Champions, a level 4 LIGHT Warrior with 2000 ATK and DEF. Stats are great, but are backed up by a lackluster effect and a terrible drawback. Your opponent cannot attack Nordic monsters other than Tyr of the Nordic Champions, which is neat, but does not allow you to create a lock with two of them in play. If there isn't another face-up Nordic somewhere on the field, Tyr is destroyed.

Considering many of the monsters in the Nordic deck would prefer to be attacked, like Tanngrisnir, and Tyr isn't really terribly strong, he's rather useless. Perhaps a copy or two could work in some builds for some beatdown, but you would usually rather just play another Nordic Beast or a tuner of some sort.
