D/Zel (ft. DB_Dragon_General)

Description (as described by DB_Dragon_General):
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.
