A deck based around tributing your opponent's monsters in order to activate your card's effects. There's a lot of combos you can do when activating the main card of the deck "Lair of darkness", for example:
-You can activate Lilith's effect to tribute your opponent's monsters and get a free trap card from your deck, which can be used with Critias to fusion summon. You can then summon Dark Diabolos since you tributed a monster
-You can also use Super Polymerization to fuse your and your opponent's cards and get a starving venom onto the field
-You can use Share the pain and basically destroy 2 opponents monsters
