The Troll part in the name stands for the powerful Sedge Troll, and Disco stands for the disk with tentacles, Nevinyrral's Disk. The decks game plan is to use the disk to blow up the world, except for your trusty trolls that is. The Trolls instead regenerate to fight another day and continues to beat your opponent senseless while all of his or her stuff has been blown to pieces.

That is the core of this deck, but other than that you can build it quite differently using either classic beaters like Hypnotic Specter or go all in on regenerating creatures like Uthden Troll and Clay Statue. If you want you can also splash blue for more control elements if you don't think the disk is enough.
