Boros

With apologies to DT, unfortunately Deflecting palm has never really shined.
Forth Eorlingas! is just one step too good and is a strong payoff to splash. Form a posse supports the boros themes better while still being strong. it also gives more inter-play with each token having an ability. Technically, it is increasing the curve, but in a way that supports the boros approach of small, many, good creatures.

Red

Detective's phoenix is a cool card, it also supports aggro and can help red decks get a burst of potential later via the recursion. Dockside is situationally good but has never really popped off. Again, it is increasing the curve, but should hopefully support a late game red approach.

Azorious

Ojutai's command is just not cutting it.
cards not replacing it:

• Fractured identity is too strong as it is a full 2 for 1.
• Shorikai, Genesis Engine would be cool but it fufills the same role as sphinx of the rev.
• Prodigy's prototype is not really otherwise supported, but was a close second.
• Monk Class, interesting but pushes a theme otherwise not really supported.
• Assimilation Aegis is slow, creature only fractured identity.
• Disorder in the court is close, but touches izzets themes a little much. but this could change.

Regeneration Restored is interesting and will be swapped in for now to try out. But it is a tenuous swap.

Selesnya

Pledge of unity is still borderline, Same goes for Ajani, the greathearted. I will swap in seraphic steed to see how it goes.
