This is a few adjustments that needed to be done after some testing. Red aggro turned out to be a bit too weak and didn't have tools.

Bonesplitter provides a tool for aggro decks to punch through some of the bigger walls. Urza's Saga was identified as a clear power outlier. The switch was clear.

Reckless Charge provides some oomph that was missing from the red aggro deck. Also plays well with Dreadhorde Arcanist which needed help. (Another plus for bonesplitter btw)

Magma Jet just wasn't cutting it. Cut it for Searing Blaze for a bit more oomph.

Inspiring Overseer, whilst not a power outlier, is incredibly efficient. Just needed to tone it done a tad by replacing it with Priest.

Nyx-Fleece Ram does its job of walling a littttle too good. Wanted to encourage more aggressive play so replacing it with all that glitters gives the enchantment theme quite a bit more punch.
