Here it is... the Teana Open!

[Zechnophobe]

Marauder vs Bear:

Start of Turn:
IF: Maurader is more than 2 squares away from bear He waits.
Bear moves.
If he can use no retal ability, he moves to position to do so.
IF: Marauder is not more than 2 squares away from bear, or is unable to use no retaliation ability: He runs away, out of range.

He shouldn't lose, he may not ever even get hit.

Speaking of.. how Does a Polar bear lose to a Thorn Hunter? ( mean, at all, you have it as 3-2 only, like it is a close combat or something).
PB has higher init, so it is similar to Marauder. Wait at beginning of turn, and then after thorn moves, move towards it.

Activate running only once you are 4 squares away. Should be a snap. It isn't like the thorn has inifinite retreat distance to keep backpedaling through.
