The deck will probably work better in pioneer, even despite not having as much redundancy. Its a mardu creature deck featuring solemnity+luminous broodmoth combo to infinite burn opponents down to 0.
Basically with the addition of either Kroxa, Titan of Death's Hunger or Fanatical Firebrand, Solemnity and Luminous Broodmoth essentially makes our ground-bound creatures unkillable. You could be normal and use this for value, or, you could take advantage of creatures that sacrifice themselves to deal burn damage and deal as much as you want. I know, you're probably not used to seeing Kroxa as a burn damage creature, since it is very conditional, but when you can cast him for BR and then bring him back as many times as it takes, they will eventually run out of cards to discard and will therefore have to take a bolt each time.
Yes, this is a 3 card combo, so it's not going to be super consistent, but that is alright because we also can just play a value plan on top of this where the combo is just incidental. We will want 4 Thoughtseize for certain, to disrupt the plan of other decks and also to protect our combo. To dig through our library, the most efficient card in these colors is probably Discovery//Dispersal. Because our draw power isn't amazing, I have decided to load up on discard and removal to focus on knocking opponents off of their plan primarily to give us time to reach our plan. If we don't hit our combo, kroxa is always still a good card, as are the adventure creatures. Bonecrusher Giant can close the distance quickly backed up by disruption, and we have a lot of unconditional creature removal as well as fatal push. The moth itself is still a restoration angel without the combo, which has historically been an acceptable wincon for control decks. I'm not sure if this has what it takes to be good in Pioneer, but it will at least be capable of winning games. We could end up shaving or cutting Fanatical Firebrand as it is easily the weakest pound for pound card other than Solemnity. The best use it has outside the combo is picking off early mana dorks from our opponents, but we could just run more pushes and shocks if we were worried about that. It adds alot of redundancy to the combo, as its nice being a 2.5 card combo rather than a full 3 carder, but if we are moving away from the all in approach to the combo and just becoming a midrange deck with a combo built in, he could be unnecessary. I suppose if I cut all 4, Id move 2 bonecrusher giants to the main and add a 4th push along with another threat/1 cmc damage based removal.
