My dudes, I have joined you in the fold of Mono-w Bruna players. My decklist is quite similar to [mention]toctheyounger[/mention]'s, though it has some personal favourites on it. I've only played three games, so it's probably not worth reporting most of the differences (I won all three, but my meta is super casual and people are experimenting with new stuff). Allow me to regale you with some options you may not have considered:
Marshal's Anthem: In all three games, I had plenty of mana. Loads of it. Boats of mana. The game I drew Marshal's Anthem, it was a rock; I kicked it four times, bringing back Sun Titan, Grand Abolisher, Stonecloaker and Angel of Serenity. I would wager that Marshal's Anthem is good a fair amount of the time. Even rezzing two or three really choices targets is very powerful (and two targets is a mana cost similar to Bruna's).
Angelic Renewal: I drew this one game, to minor effect. I played it turn two, and a
Solemn Simulacrum on turn 4. I got a second set of triggers out of the Simulacrum, and it helped catapult me into the mid game. Realistically, this card is just a pre-paid 2 mana resurrection. But, it very much likes Sun Titan (on account of Sun Titan bringing it back into play when Angelic Renewal recurs Sun Titan). Almost all of our cards would be okay with a two mana recursion, and it also allows to 'bank' a pickup from our darling,
Emeria Shepherd.
Bounty Agent: While not as stellar as the previous mentions, I found Bounty Agent pretty good. Often, I would want to disrupt problematic generals. They can be activated in response to Magus of the Tabernacle triggers, is vigilant, can carry a Sword of the Animist, is on tribe, passes the Sun Titan test... It's not an all star, but it very much fits in as easily-recurred removal for a likely feature of your opponent's decks (they cannot bring in planeswalkers or lands, but are happy to lay most targets low).
The other main difference is my mana base. I play two allied fetches,
Terramorphic Expanse, and
Evolving Wilds along with
Myriad Landscape.
Ghost Quarter is my chosen land destruction, and the purpose for these fetches and Ghost Quarter is to use
Brought Back and Sun Titan. Many of my turns were consumed by Sun Titan recurring a fetch land. So often, in fact, I found
Gift of Estates and
Weathered Wayfarar's to be a dead draws in the games I got them. I also found the fetches to be very powerful with
Emeria Shepherd (especially in combination with
Angel of Serenity, which made threatening combat almost impossible).
Cards I want to include:
Enlightened Tutor: Finding the second half of
Scroll Rack/
Land Tax would be wild. I think, also, it gives us a flexible out against swarms (you can tutor
Ghostly Prison or
Eye of Singularity), or artifact draw/ramp/boots. The card disadvantage, I think, would be worth it.
Mangara of Corondor: I want to be able to answer anything, and Mangara can be 'recruited' by
Thalia's Lancers. Most of the time, I think it'll be one-and-done with Mangara, but it's not impossible for us to have
High Market and repeated recursion. I'm wary of Mangara being slow/clumsy, but, it might be necessary for some things, like planeswalkers. Basically, Mangara would be an ultra-slow Unexpectedly Absent/Generous Gift.
Eiganjo Castle: My friend's decks are rife with deathtouch. Hapatra snake tokens,
Ohran Frostfang, you name it. This might help some legends turn them back where they would otherwise die (Like
Linvala, Keeper of Silence, or our general, Bruna). The opportunity cost is fairly low, and could be tutored by
Thalia's Lancers or
Weathered Wayfarer. This might be too narrow, however.
