While this deck is very easy to build around, the simple fact is that no one is building around it. From where I'm sitting this list looks incredibly well poised to tackle the current meta, while also being vastly pleasurable to pilot and oppose, and retaining a very memey core concept. Though there is a lot of nuance to proper piloting of the deck, its overall gameplan is very simple and straightforward:

1) Establish strong, annoying-to-remove threats such as Haktos the Unscarred and Lavabrink Venturer

2) Give these threats lifelink via Heliod, Sun-Crowned's ability, Gideon Blackblade's +1, and spells like Deafening Clarion

3) Cast wrath effects like Shatter the Sky, Clarion, Storm's Wrath, etc to clear the board of any blockers while retaining a commanding board presence

4) beeg hoomanz smash face

Most of the nuance is introduced with the distinction between the indestructible and protection keywords. Indestructible prevents all damage to the permanent such as from Clarion, and prevents the permanent from being affected by destroy effects such as those of Shatter and of Planar Cleansing. Protection on the other hand, comes with it's own extra perks over indestructible which are important to keep in mind (such as that they cannot be blocked by creatures against which they have protection and that they cannot be targetted by such spells or by abilities of such permanents), however they have one massive relative weakness, the understanding of which is crucial to the proper piloting of this deck: protection does not prevent "destroy" effects from affecting the protected permanent. This distinction is crucial to knowing when which wrath effects should be used, as one may intuit, for example, that if they control a Lavabrink Venturer with protection from even CMCs and wish to cast a Shatter, that their Venturer would survive as it has protection from the Shatter, HOWEVER since protection does not protect from "destroy" effects, their Venturer would be destroyed.

As for the deck's sideboard, it is geared heavily to hate on the list's hardest matchup, Rakdos aggro lists popularized by crokeyz, running cat-oven and other grind-y attrition-y methods of chipping away at the opponent's life total, with Lurrus of the Dream Den as a companion. The 3 of Devout Decree helps to find the needed answers and threats while dealing with theirs cheaply and without hope of recursion. The 4 of Leyline of Sanctity will often produce very deterministic results in the matchup when in the opening hand as while it does nothing to prevent the attrition of Cauldron Familiar and Serrated Scorpion, it does disable their main engine, Priest of Forgotten Gods. The playset of Grafdigger's Cage is present to not only shut off cat-oven, Kroxa, Titan of Death's Hunger's escape, and Lurrus's own ability, it also demolishes a variety of other decks rising in popularity, such as decks built around Gyruda, Doom of Depths and Winota, Joiner of Forces.

I present to you: the aggro deck that flies under control and gives them no chance to stabilize with wrath effects, has strong tools against typical aggro decks, has answers to most of the meta, is resilient to the removal of midrangey decks, and still dies to Embercleave. Have fun!
