D/Zel

 is an archetype of FIRE and EARTH Machine monsters created by Smooth Operator and was conceptualized by DB_Dragon_General on Pojo. The archetype's prompt is read as follows:

"The "D/Zel" archetype consists of EARTH and FIRE Machine monsters, with a bit of a Mad Max/post-apocalyptic scavenger vibe. Its Synchro monsters cover a diverse array of Levels, each of which can confer additional effects to High Octane D/Zel Dragon. The strategy could be described as a control/stun build, relying heavily on Spell and Trap cards to slow things down until suddenly exploding into a powerful end game. The S/T cards it fills the GY with have effects that trigger if they're banished by another effect, such as using High Octane D/Zel Dragon to Special Summon an Extra Deck monster."
