Cosmic

This is Cosmic!

This dragon is what's called a Mirer. (He's specifically a modified Mire Fisher.) He can train 2 other dragons in the Mire, if you know how to use him. Those 2 dragons can be either 2 permas (if you need your own level 25), or 2 fodder which can then be exalted for profit. The most profitable level for exalting is generally 5-7. (A bunch of level 5s is most efficient unless fodder dragons are especially expensive.)

Mire enemies that scratch:
Armored Colony
Fungal Garden
Furry Fiddle
Marsh Kelpie
Molten Wartoad - boss
Muckbottom Catfish
Poisonous Toridae
Scythe Kamaitachi
Shellion
Sickle Kamaitachi
Silt Wolf
Swamp Wolf
Southmarsh Podid
Venomous Toridae
Vilevenom Kelpie
Wartoad - boss

Mire enemies that meditate:
Acid Ant
Blackwing Croaker
Brilliant Psywurm
Common Podid
Heartred Croaker
Ink Ant
Lion's Mane Seeker
Mistwatch Shellion
Mossy Cerdae
Psywurm
Salve Kamaitachi - contuser
Wetland Unicorn - contuser
Whisper

You'll want to start on a 3 pack with entirely mediating enemies. (2 meditating enemies also okay; you just want a maximum of 1 scratching enemy so you don't lose a ton of HP while getting breath together to use eliminate.) You will also want to watch out for 3 packs of contusing enemies, since contuse lowers your damage and can mess up your first round.

First round:
(Optional haste)
Rally
Scratch
Scratch (same enemy)
- monster turns -
Scratch (kill same enemy)
Scratch (new enemy)
- monster turns -
Scratch (last enemy)
Eliminate
Eliminate

And you win!

Next round:
(Optional haste)
Rally
Eliminate away!

The way Cosmic has his stats, he can rally+eliminate any enemy that isn't a boss.

I would run from any wartoads you encounter while training fodder, and don't be afraid to refresh the page if you're getting low on health. (Refreshing starts you over without losing energy; if you use the "flee" action, your dragons lose some energy and you may have to feed them.)
