Yeah, you want the ogre to be low level so whatever level he drops at just roll with it. Same with your team - you can even put evolution mats in your party, since you'll be doing 1hp to the dublits even if your regular puzzlemon were there.
I actually prefer to have as mono-color as possible so you can burn a sync dublit down quickly. The way it works is as long as your HP is above 70% of your total, you'll survive any
single fatal hit with 1 hp. Assuming the autohealer is high enough, you'll be auto-recovering enough HP each turn that as long as you make at least 1 match (doesn't have to be an attack) and you don't eat two dublit hits in one turn, you cannot die. You'll need to stockpile orbs of your main color in the corners before hitting the 4th and 5th stages - you'll likely have at least 2 synced, and it'll take 10 hits to kill one. Here's a video of how it goes:

The other method O4rfish mentioned is running with a Shiva buddy, or I guess now also the Top Droidragon. The two of them have the active skill that brings enemies' defense to zero - this will one shot all of the dublits with any normal puzzlemon - and it carries over to the next stage if you kill everyone on the screen. You need to stall on the first or second stage until the active is ready, it's 22 turns so I still recommend a mono-color team so you can just match off colors and stock up the main color as you wait, Shiva is red and Droidragon is green, but really as long as 5 guys are the same color that'll 2-shot the dublits and 3-shot the dubmythlits if something goes wrong and you need to clear one during your final waiting rounds (boo sky combos)
EDIT: ^^^^^^ yeah what he said.
EDIT^2: If you want add me (number in firstpost, I just cleared out some friendspace) and if you poke me here or with an in-game mail I'll switch to my Siren if you don't have one on your list already.
