This build is called the "Mire Flyer" build. Its main purpose is to allow a dragon to train 2 other dragons fairly quickly solo, either to help kickstart a full proper team or to train dragons to exalt/sell for munie!!
(Most people train fodder to Lv. 5-7 because it's very quick. I go up to Lv. 10 because I have no life.)

It isn't very well suited to farm for Coliseum drops because it's essentially a glass cannon build. Once you have more Lv. 25 dragons, you could potentially add this dragon to a proper team, but how well they'll perform is a bit iffy because they're kind of a one-trick pony. >v>;

I'd imagine using 3 Mire Flyers on a team would be very hilarious though-

• Put this dragon in the middle slot. I dunno why, but in my experience, they just get hit the least in this spot... for some reason? You're gonna want to let this dragon survive as long as possible since they're doing all the work.
  • With that said, don't worry too much about the other two dragons getting KO'd. They'll still get EXP and revive the next fight.
• Pick a Coliseum venue. I recommend the Lv. 24 venue, The Mire, since this build is specifically called the "Mire Flyer" build, but it should(?) work as early as the Lv. 20 venue, Boreal Wood.
• Use Haste to go nyooooom and then Rally to get stronk.
• Use Scratch for 4 turns, then use Rally again on the 5th to renew it.
• You should now have enough Breath to use Eliminate, so kill off whatever's left with that.
• HASTE + RALLY + ELIMINATE EVERYTHING TO DEATH >:3
• If you encounter a boss or run way too low on health, exit the venue and then come back if needed. Mire Flyers aren't very good at combatting either of those things by themselves.
