I got By-Ulf first of this trio. Then Grevle and a last Scrubbear joins in. In a no red 3* tournament which green hero is usefull in defense ? By-ulf is Paladin, very usefull as tank but his defense is low. Even after some emblems. Grevle has a great defense stat but his heath is low. I don’t know where Scrubbear fits in. I think grevle is the best of this trio but others may chims in.
My other rare greens are Belith, Mnesseus, Hisan, costume Isshtak with his defense down.
Agreed with @BubblesUK; I also don’t rate By-Ulf virtually at all… I levelled him thinking he’d be awesome for tournaments but really don’t use him ever…
By-Ulf is a staple in my green Challenge Event team (cBrienne, Ishhtak, By-Ulf, Mnesseus, Berden) but I’m not particularly fond of him for defense. I had him emblemed at one point to +20 but after 3 tournaments of D, C and C ranks I didn’t feel like being the guinea pig any longer to keep gauging his potential. I’ve stripped him since in favor of better paladin 3* (Tyrum, Gunnar and Ei-Dunn come to mind).
For Shrubear he can be very tough to take down after the fires but he is also dispelled easily by Mnesseus and Tyrum. Personally I think he’s a much better offensive 3* and only wish I had him for that.
Grevle is only one out of those that has given me significant trouble in recent 3* tournaments where healing is allowed. He’s basically a mini Heimdall without the resurrection, his defense stat is the highest in 3* rarity and his boosted HP makes him much more difficult to take out than he seems. He’s the one I’d choose to use on a 3* defense team out of those green heroes.
Grevle is best. Bi-Ulf is sub-par & only heals/shields 3. Burns bright then crashes if you haven’t won. No such shortcoming w Grevle or Shrubbear. But, I also have left my BiUlf at 1/1 so maybe consider the input from those who’ve used him.
