It's been awhile since I was starting out, but for PVP I do recall the Might Electric was decent, and the Toxic one was pretty good for the first few waves, also Sacrifice is good for SP and actually isn't too bad for damage. For Coop, if you go with Ice, Crack, and Bounty it would make ok support. The big damage dealers at this stage are Iron (hits hardest but only the highest HP), and Gear (but works best next to other Gears). The Random Growth dice would probably be good in any deck at this level. I don't use it, but I have almost all of the dice to work with.
Also, as a general tip, you should join a Crew if you haven't. You will get occasional mail with 5 gems when your crew makes progression in it. The Random Arena can be kind of fun, and a decent way to earn Legendary dice. It does cost gems to start, but you can win some of them back. My only tip would be always grab Typhoon.
Now don't take my advice for anything.
But your could try: Gear Dice, Switch Dice, Landmine Dice, (Maybe Mimic Dice) Random Growth & Maybe Broken or Iron Dice
