Cassette Beasts: "The Midnight Train" Side Quest Completed

I have beaten 50 carriages of Magikrab's Gauntlet in Cassette Beasts. In other words, I have completed "The Midnight Train" side quest.

I was already around level 180 when I started the Gauntlet, while the Gauntlet starts at level 50+ and then gradually levels up as you progress, so it wasn't too difficult.

However, due to the random encounter nature, bosses can catch you by surprise with their gimmicks. For example, one of the bosses I encountered was Poppetox, whose gimmick punishes AoE attacks due to the Effigies. I had Kayleigh with me when I encountered Poppetox in the Gauntlet, and both our starting tapes, Umbrahella and Decibelle, have the Echolocation sticker, which gave us the Multitarget status at the start of battle, so for 3 to 4 turns (Kayleigh's Decibelle's Echolocation sticker has the +1 Duration attribute) we took damage from our own attacks. Ouch.

There is also the boss for Carriage #50, Magikrab, who battles like an Archangel due to the Summoned Power status, He will summon random monsters with the Ghostly status as backups. It took me two tries to defeat him.

I brought Meredith with me when I fought Magikrab. In my first try, we did not fuse, and his Angelic Attack and one of the summoned monsters ended up defeating Meredith, including her human form, while Magikrab was still not close to being defeated, so I had to retreat and then battle again. I chose to fuse with Meredith this time and the battle became much easier.
