Don't know if it is relevant or if anyone mentioned it, but there was a Bant style list that got 4th in the last SCG. It seems more like a "Bant Midrange" then a Maverick since it doesn't even run Thalia because it has its own share of Brainstorm/Daze/Force. It does run 4 Knight, 4 mana dorks (3 Noble, 1 BoP), 1 Sigarda, 1 Pridemage, StP, and Library which makes it kind of overlap. I know we don't go down the Bant path here since it has its own space, but I think there are things in this list that are interesting from a Maverick pov.
1. Kessig Wolf Run:
In a Punishing Maverick red based build we probably can't make DRS work as well and we lose Abrupt Decay. We gain reach and burn like Punishing Fire. If we run a Cradle already and can produce a non 0 amount of mana, could Wolf Run provide a way to attack into a TNN?
This also makes me think of other Red based lands we could try out. The non Scapeshift land based deck in Modern looks to Sunhome, Fortress of the Legion (2RW tap: double strike) and Slayers' Stronghold (RW tap: +2/0, vigilance, haste). With that deck that use Amulet triggers to generate a lot of mana really quick to cast like a turn 2 Primeval Titan to do further shenanigans with. I think Sunhome is too expensive for us but Slayers' Stronghold seems cheap enough. Radiant Fountain is used there to gain life, but this can be recurred and I don't think it fits well with us unless you run Life from the Loam.
All this being said, I am not sure if just making a 20/20 ML token is just strictly better.
2. Retreat to Coralhelm:
We discussed this as a combo card with Knight but didn't think the manabase could support the black and blue. He was able to use this and fetchlands to make a decent amount of mana and then make a Kessig Big Knight and lethal swing. See #1. I still would like to see how the White Retreat works since it gives play against Miracles in uncounterable tokens to chump or attack.
3. Sejiri Steppe:
Probably not what we are looking for seeing as it is a enter tap land which is not great in an opener (can't even cast t1 Mom). Just makes me wanna look back and find other lands I may not have tried or been aware of.
