I built and tested a preliminary idea for your challenge, changed it a few times, got something I'm somewhat satisfied with. I tested without an opponent (Basically, I assumed that the opponent made standard plays like I would, had no shields to stop attacks, and didn't really do much in the way of card effects), and by paying gauge the correct way and intentionally sending certain monsters (Mostly Dragoarcher) to the drop zone by calling over them (Using him for the draw and not much else, basically), I was able to get Stormschlag off on turn 4 in about 3/5 games. So in a game against a live opponent, I'd say you're likely to be able to do so roughly by turn 5 in a roughly similar number of games.

Here's the list:

Raging Tempest

Flag: Dragon World

Buddy: Thunder Knights Leader, Kommandeur Fahne

Monsters - 23

Size 2 - 11

4x Thunder Knights, Drum Bunker Dragon

3x Thunder Knights, Halberd Dragon

4x Thunder Knights Leader, Kommandeur Fahne

Size 1 - 12

4x Thunder Knights, Dragoarcher

4x Thunder Knights, Iron-fist Dragon

4x Thunder Knights, Main-gauche Dragon

Spells - 17

4x Blue Dragon Shield

3x Dragonic Aura

3x Dragonic Grimoire

4x Green Dragon Shield

3x Thunder Formation!

Items - 6

3x Gargantua Blade, Black Smasher

3x Steel Fist, Dragoknuckle

Impacts - 4

4x Dragobulk Stormschlag

Notes:  Do NOT be afraid to play over a card on the field if it will better help your position. If you have 2 Grimoires in hand at start of the turn, charge 1. Play as many cards as you can before playing Grimoire. Don't worry too much about holding onto Dragon Shields, you won't need them THAT much... If you have to discard it or gauge it, oh well. Honestly, I was thinking about dropping Green to 2 to make room for a 4th copy of Aura and of Thunder Formation!, so don't sweat too much about the shields. This deck's monsters are basically best left on the field to be destroyed. If you ever build up the 10 gauge to do it, you can Thunder Formation! and then Stormschlag... Which might be possible while waiting on Stormschlag... Since the deck runs 4, you'll likely get at least 1 early, this one can be discarded if necessary, it's highly unlikely you won't be able to get another. And in the event that you can't, well, it's Thunder Knights. They specialize in beatdown and defense. And you can always just use True Thunder Formation in the event you don't get Stormschlag. So yeah, that's about how it goes. I'm not saying the deck will win all that often. But it'll certainly be capable of dealing 5 damage with Stormschlag in most games.
