I mean sure, creating dark orbs + jammers sounds like a total troll but considering his LS, I honestly think he can works well in many descends where you can turn the disadvantage orb troll into your ally. Alot of bosses and none boss can turn almost over half of your board into jammers / poison. Which means this monster means he's born for these dungeons! 3 jammers = 4x attk and 9 = 10x also! 2x attk when attk with 5 colors, so ideally he can literally deal 200x dmg with another Fenrir friend . Not to mention his AS is on a rather short CD even at lvl 1. Put one more Fernir on your team and with a friend lead. It pretty much ensure a constant jammers on your board. Not only as leader he's useful, but his stats as sub is pretty appealing to me as well you can use his skill to combo into another monster who can turn jammer into an element orb. Also the fact he's a devil + attacker makes him really easy to set in a team with. Sure im not good with numbers, but just by what he's showing on the surface I believe he can be a pretty solid leader. Not saying he will be a "new meta" (which he could, potential is there). But I just think we should give it a chance.
