Okay so - I beat the first guy with no problem
But Sariel’s Velocirex is a nightmare. It kills my entire party in one hit and if I use my death revengers in my starting lineup, then I don’t have them later to use death roulette when things look bleak.
I don’t know how to beat her. I lost worse than I’ve ever lost before. She had like 10 monsters left!!!
Every single monster she has is a super epic or legendary with max stats that hits for 1100-2000. How the hell do you win?
Is this the one with the ice ? I think I used sleep , and dream hunt
I tell you what mate , get puffoxin (it has death roulette )
If you wanna spend your time (takes abit of time ) keep using the death roulette hehe , amazing
I beat the the grand champion with my puffoxin , after like 50 or so battles my puffoxin got through and beat like 5-8 monsters then left the rest of monsters to hard work .
But it’s luck what I used 
I use Puffoxin AND Rhynobrawl who both have death roulette. I’ve not been lucky with it. I use it a lot as a last resort or to take out an impossible monster like Snogun with his retarded time strike of grand doom. But a lot of the time they end up killing themselves. I think my death roulette has killed my Duecalon more than any other monster. I’m surprised he hasn’t rebelled and left my team.
No, she’s the Lightning one. Her monsters have stun revenge so whenever I kill one then the rest of her team kills like everything I own before I can take my turn. I think I need to somehow strategically kill every monster of hers except the ones with stun revenge - but she also has ones with stunning entrance … It’s impossible
where do you find rhinobrawl and/or puffoxin?
I think one of the key strategies in this game is picking the correct targets and leaving low level threats alive so dangerous creatures don’t stack up on the field. For sariel I opened with the two-star protect/stun absorber found in one of the earlier maps(stegospike,I don’t remember where exactly) and my sweeper vulcaraptor ( super epic:throw, timestrike, bloodthirst), a team acceleration (leobolt), and finally rhinobrawl for poison to set up later drops and tank (he is definitely one of the best two stars and a staple for any team). If you have a fast sleepkiller you can take out the velocirex before it gets going. Next drops on my side is a healer and then a eat poison squad.
The goal of the set-up was to ramp up vulcaraptors blood thirst with throw and then keep him alive so he can just sweep the entire team. I left Sariels ninjastorm, a twostar flier, and a random three star alive for the entire fight and just kill whatever spawned in the 4th spot. Vulcaraptor ended up getting 7 kills before finally going down, the rest was just cleanup. Since your opponent will always have 4 creatures out, you should leave the least threatening ones alive so they only have 1 dangerous creature out at a time. Kill anything with bomb, survivor, bloodthirst, protect, sleep, eat poison, etc. The ones with only attack abilities are usually the least dangerous because the big damage come from special ability interactions.
Thanks. Yeah. I can’t kill the Velocirex quick enough because you need really high speed any unfortunately my powerful killers aren’t fast enough. But I manage to knock him back with Remus, literally 2 seconds before he attacks.
I’ll have to try killing whatever spawns in that spot next and keep doing that, but the stunning enter abc’s always throws me. I have one stun absorber but he’s water element :/, I’ll look for stegospike. The name sounds familiar, maybe I have him too. I’ll keep you posted.
Ive finished first two with ease. 2nd one I won with accelerated last bite of don penguini. So maybe a monster with same skill will.be good.
Now on to my 3rd one. 
goodluck to all of us
