Executive Summary: The "All-Tuner" Paradigm

The "Kewl Tune" (OCG: Killer Tune) archetype fundamentally deconstructs the Synchro binary. Unlike traditional decks that balance Tuners and Non-Tuners, Kewl Tune consists almost exclusively of Tuners. It solves the "bricking" issue via the "Hand Synchro" mechanic: if a Kewl Tune monster on the field is used for a Synchro Summon, a Tuner in the hand can substitute as the non-Tuner material.

Strategic Edge: This mechanic creates Information Asymmetry. Opponents cannot accurately predict the Level of your incoming boss monster, as the second material remains hidden in hand until resolution. While the deck imposes a strict "Tuner Lock" (preventing access to Baronne/Savage), its ability to execute "Turn 0" interaction via Kewl Tune Clip makes it a formidable rogue contender.
