Yubel Deck

A Yubel Deck primarily revolves around the use of the 3 'Yubel' monsters, and supporting their evolution to their next level, while preventing your opponent from getting rid of Yubel until you want it to be destroyed, and thus evolve to its next level.

Yubel Rush Decks
Yubel Rush focuses on quickly summoning Yubel, and using certain effects to destroy it in order to summon the next level monster(s). As Yubel is difficult for your opponent to destroy, this deck speeds up the player intentionally destroying their own Yubel. Cards such as Man-Eater Bug and Thunder Crash can aid Yubel's initial destruction, allowing swift summoning of Yubel - Terror Incarnate. As Yubel - Terror Incarnate's effect activate as soon as it leaves the field, cards such as Compulsory Evacuation Device can aid the summoning of Yubel - The Ultimate Nightmare. In order to augment Yubel's protection and DARK theme, cards such as Obsidian Dragon and Legendary Fiend can be useful, as well as the mandatory Mystic Tomato, which can automatically Special Summon Yubel as soon as it is destroyed in battle. Phantom Skyblaster can be useful, combined with protective Trap Cards, in order to damage your opponent's Life Points as well as summon Tokens to be used for Yubel's Tribute Cost. Phantom of Chaos is also useful to emulate Yubel's ability if it is in the Graveyard.

Weaknesses
Cards such as Rainbow Veil and Getsu Fuhma can pose problems in terms of Yubel's effect being negated and Yubel - The Ultimate Nightmare having no effect when it is destroyed, and Angel 07's effect-destroying ability pose serious problems for Yubel-based decks, especially seeing as how all three incarnations of Yubel are completely devoid of ATK and DEF points.
