| Degenerate |
In the rules of Duel Masters, when the top card of an evolution creature is removed from the battle zone, the creatures underneath it remain. Utilizing this, powerful finisher creatures can be put into the battle zone in the early turns of a game.
Originally, it focused on using Royal Durian from the Nature Civilization. However, after a ruling change about "Cards" (i.e.: targeting them as removal) in January 2014, cards that specifically removed other cards in the battle zone such as Senju Splash or Shadowwave Cyclone began to form a Water Darkness Degeneration deck type.
Before January 2014, creatures that remained in the battle zone under the evolution creature still had summoning sickness if they were degenerated.
"Degenerate" is not an official term like others such as "Sprout" and "Explode" aren't, and isn't used in other trading card game slang like "Bounce". However, the term is sometimes used in official sources or the CoroCoro Comic to explain the decktype.
In an example article of CoroCoro Aniki Volume 5, the following Degenerate combo was introduced;
- 1) Summoning or invading Gachidive, Eureka and putting VAN Beethoven, Zenith of "Shura" underneath.
- 2) Attacking with Gachidive, and using S-Rank Invasion to evolve into Adamski, S-Rank Space
- 3) When one of your other Water Commands attack, you move Adamski onto it. This leaves your VAN Beethoven, Zenith of "Shura" in the battle zone instead of the Gachdive with an invalid creature underneath it.
