This explosive combination centers around redirecting self-inflicted devastation to obliterate your opponents. When you cast Volcano Hellion, its enter-the-battlefield trigger is instructed to deal a massively lethal amount of damage directly to you, but the presence of With Great Power . . . on the board gracefully intercepts that incoming damage and forces it onto your Boros Reckoner instead. Because Boros Reckoner triggers whenever it is dealt damage, it immediately turns around and funnels that exact same astronomical amount of damage straight at an opponent, closing out the game in a single fiery burst.
