Spider has always been my weakest dungeon and I have barely been able to scrape past the first 18 levels. I am currently stuck on level 19 and have been trying to take the approach of keeping the spiderlings alive and burning them with Ultimate Galek (using Incr Atk from Doompriest). I simply can not keep my team alive or keep the Spider's TM under control. 

I have tried using Paragon to distract the spiderlings, I have tried using burners from multiple champs including Achak. I simply can't get past this stage on manual, let alone auto as required by the Arbiter mission. I have my Wythir built to solo the stage hoping to get by that way but it doesn't work (in a toxic set, resist is 230, ACC 310, speed 200). I have Drexthar ready to summon but I was hoping to save that for a future Champ Chase event. I have never pulled a Cold Heart. I'm at a loss, any suggestions given my roster?
