I would say his biggest use will be arena, although it's unfortunate that he's ATK based and not DEF based :/

Thanks, i guess that might be one place, struggling to get my head around his use really.

Agree that he looks very squishy.

I think a potentially great champ in arena and DT.  I use a combination of Warlord and Astralon to CC the floors and my 5th champ (skullcrown or ignatius currrently) is for damage.  Slotting this guy in on tough floors (double mortu or siphi/rotos/rotos) could be a great fit.  Need to speed tune and manual to get the aoe stun and maximize his potential.  It may be even tougher to get  that AOE stun to work in tag, but I haven't really pondered it that much.  Just looked at his skills today for 1st time lol. 

I get all the fusion and fragment summons done I have no idea why anymore. Tbh I don't even know what this guy or the last one(cyble?) does.

I only looked at his kit tonight as well, i want him to be good as i am a GOT fan and it is clearly the hound 

I would build and book astralon 1st, but this guy will hit harder.

Then it may be your Astralon build that's the issue... mine does CC and damage both, hits like a truck. If this guy's going to hit even harder, they could be fun to use together!

I've found myself going for all the legendary rewards from events even if I cant see any immediate use for them. Theres always that risk that at some point in the future they'll be rebalanced into a top tier uber champ

*Looks at 50/50 Pyxniel full scroll in the vault* 

When your day comes I'll be ready!

lol@pyxniel

I summoned him to pick up another lego book, and straight into my vault.

I dont do every fusion, but the last few that i have done the champs have gone into the vault.

Like you say they may get reworked so its worth keeping them
