Loaner deck from the April 2025 Duel Triangle event.
Official description:
Difficulty level ☆2
First, strengthen your position by using the effect of a card like "Heroic Challenger - Morning Star", then fend off your opponent's offensives with a "Heroic" monster capable of interrupting them during their turn.
Once it's possible to strike, swiftly end the Duel with "Heroic Champion - Claivesolish", Xyz Summoning it and using its effects to reach insanely high ATK.
When you have the choice, going second is also recommended. Although this enables your opponent to pressurize you, this Deck benefits from being able to attack straight away.
