Ok, first thing you need to know about is list view, a much more convenient way to show off all your monsters. It’s the top right button in the monster menu.
Now for your team. I’m seeing a bunch of crappy monsters in your team, and a bunch of excellent monsters sitting in your bench. You need to ditch Moltenpede, Djinzar, Terrorex, Keeperdragon, Halodrei, Spinorex, Emberzard and Gnashjaw, and replace them with Searguard, Galvbane, Horrorclaw, Atlanteon, Shadowbaron/Luxking, Dreadfish, Carnofrost/Luxyrion, Deathwarg, Frostrider, or Armavolt(your choice of which ones). I GUARANTEE you will see a substantial improvement in performance.
Now your frontline. The little problem is, Noxdragon and Sanctallion are pretty weak options too, but I understand your need to use them since you don’t have many legends. You can keep sanc since his cloning stun revenge definitely comes in handy, but nox needs to go, I’m sorry. Without his links he’s just not of any really use other than a highly expensive accelerator.
Now, your ace in the hole will be Soulstealer. I myself use him all the time for buffed events like the scb, there’s simply no better man for the job. Also, Frostrider pairs extremely well with him- just use death sentence, then one on one, then switch into a purifier and let the enemy’s clocks tick on down. Heck, you can even stick a megabomber or two in the frontline to capitalize further on all the spare time frost provides.
That’s all I can provide for now, hope it helps
