The core of the power in these two decks belongs with Radiant Destiny.

In an attempt to play a human tribal deck with an Exert theme, I have built two prototype decks that I'm sure have been built by many before. Both decks have the benefit of consistency of play and fast battlefield presence. The consistency of play provided by the mono-white deck is matched by the sheer power of the creatures available in the red/white deck.While it plusses up your humans, it can eventually give them vigilance as well, as long as you can accumulate 10 permanents. To help with this, there are several removal-based enchantments that build toward that end. The mono-white deck uses Angel of Invention to plus up your creatures at the higher end along with Settle the Wreckage to wipe your opponent's board. Both of these additions make the mono-white deck powerful and easy to play.The red/white deck really only changes a few things. It adds Abrade, Combat Celebrant, and Glorybringer. Of the three, Combat Celebrant is probably the most powerful (given its ability to add another entire combat phase) followed closely by Glorybringer. Exerting both will allow you to untap Glorybringer for another attack and another exert trigger. The benefits of this deck are obvious-additional combat phases and power on the higher end.The sideboards, of course, are meta-dependent. I recommend Fragmentize and Gideon's Intervention...these are great second game cards.I'm curious what you think. Try them out and see which one you like best.
