If you think about it with a skill, remember that:
This Skill can only be used if you begin the Duel with a Deck that contains 8 or more "Destiny HERO" monsters and no monster other than "Destiny HERO" or "Elemental HERO" monsters.(Extra Deck is not included.)
That skill would be bad for stall burn even without the monster restriction. You don’t want any Destiny heroes, you don’t want backrow removal in your deck. You just want the tower to stay there with 4 counters.
Even then, the skill isn’t all that if you have a way to stall until the next turn (ex: Battlin Boxer Veil, Stegocyber, etc.) and happen to have or draw a card with an effect (ex: Lighting Vortex) to destroy Destiny HERO-Dreadmaster.
