I dropped 1 Fairie Macabre for an extra 1 Lone Missionary, mostly because I only own 2 Fairies.

I further tinkered with the list by dropping Quicksand and 1 Rhystic in favor of Azorious signet and seal of removal mainboard, and dropped 1 circle, 1 Holy Light in favor of Kaerveck's Torch and Palace Sentinel in sideboard.

Doing well June 2018: destroys Boros Monarch and looks like if Rhystic Circle comes on line fast enough, shuts out any strategy that inflicts heavy amounts of damage from few sources.

Older list with some interesting variations:

This shell can go in many different directions, and has many flex slots. A few cards to consider include:

Quicksand
Ulamog Crusher

sideboard:
Momentary Blink
Escape Routes
Dispel
Kor Sanctifier
Relic of Progenitus


Many ETB cards could be added as 1x. See Boros for very long list, but here are a few that are particularly interesting in Rhystic Tron:

Pit Keeper
Prosperous Pirates
Sage of Epityr
Shrieking Drake
Silver Drake
Strands of Undeath
Whirlpool Rider (!!!!)
Whitemane Lion
Wispmare
