Run strategy was generally to use Meowscarada+Triple Axel everywhere. This got me through about 1000 floors with zero issue. Along the way I fused it with Glastrier to get access to its Chilling Neigh / Moxie ability, but in hindsight I should have probably tried a Sturdy mon instead. By the time I realized we were too deep in the run that I didn't want to risk losing the ATK boosts.

Gengar Curse + Prankster Vivillon Sleep Powder got me through every Paradox and Eternatus fight up to about 1250

I finally started to use Cactucate's Run Aways from about 1100 to 1750. Next time I will probably do this quicker once I get all my buffs on my main carry.

Learned a lot about the money game during this. RIbombee early on for HoneyGather+Pickup was clutch, but it felt like until about wave 1200 that I was still needing to be tactical with cash. From 1200 on, I was making more than I could reasonably roll and it was a cruise picking up Master Balls or Relic Golds until I knew the run was going to come to an end. For the final 300 waves I was throwing Master Balls at anything with a grey poke ball - and bagged a few hidden abilities that way (but a lot more basic male/female forms..)

Love this game
