This deck focuses on giving bonus power to Benedict with Nepherli.  If you place two Nepherlis on the field, that makes Benedict swing for 16k, stand himself, and swing for 11k.  Naturally, one of those (I recommend the second swing) will also be boosted.  You swing Vanguard first with this deck and apply the bonus power of all power (and if the attack was blocked, the bonus critical) to Benedict.  In the previous Nepherli example, this makes Benedict swing for 21k 2 crit and 22k 2 crit in the same turn when only hitting a single critical trigger.  Pretty legitimate pressure.  David is there to make 21k rows and to use counterblasts, since the deck is light on them.  Glory Maelstrom is a better late game card than Tri-Stringer since he can negate perfect guards, and Tri-stinger doesn't have much synergy since it needs to attack third to unflip.  Tactical Veteran Commander inflicts one damage to you to enable Glory's Ultimate Break and increase your odds of healing while shuffling triggers back into the deck.
