I don't have a list online, but I can give a quick rundown what to look for: said Boros 2-drops, and the white effects that get a 2-or-smaller-cmc (or 3 or less, 2 or less power, etc.) back from the graveyard. There's surprisingly plentiful amount of both around by this point. Then just add anthems to make the punch bigger... and... well, that's about it. Other than that deck doesn't have anything too interesting, most of the rest is just the usual draw/removal/support.

Sarkhan, Dragonsoul at a glance looks like your typical awful intro deck walker but he is putting in work with my increasingly Sarkhan tribal Ur-Dragon build. The +2 is surprisingly effective against many tokens, mana dorks, and OH GOD NO dorks like Elvish Piper. His -3 has become so much more useful with the advent of no fun allowed ability walkers, and that last ability is a 3 turn clock in a dragon deck. This Intro Deck piece o' junk is a 3 turn clock. That's like feeling threatened by a Mahamoti Djinn or a Shivan Dragon. Like, unlike Sarkhan Unbroken he can realistically ult. The only things that are a bummer is I feel he's 1 mana too high and that he didn't get a tutor card. I can't believe an intro deck walker is putting in work for me, at least in a casual setting.
