This hack is a relatively straightforward, no-nonsense one that isnt the most inventive or imaginative mod we could find but it adds all of the extra levels and items that non-Japanese players would never have been able to access otherwise
Running it alongside The Reaver Cleaver and Beamtown Beatstick et al is of course going to fuel it reliably, but there wont be a game where this doesnt trigger multiple times a turn cycle
Jeskai does give us access to a number of untap effects, so even a simple Freed from the Real on Liberty Prime would help mitigate its costly energy generation effect, but we were probably planning to do that anyways in Dr
As for Clarion Ultimatum, the sorcery can do some really powerful things, but we also had a lot of games where it rotted in our hand while we tried to find the mana to cast it, and also a few where we had the mana but didn't really have any good targets (casting a seven-mana card and getting a Birds of Paradise, a Noble Hierarch, and three lands for our trouble doesn't feel all that good)
a resolved Consecrated Sphinx is still incredible, but its just not the tilt-inducing powerhouse it was in the early years of Commander
Play Megrim next as well as one of your draw/discard creatures such as the Cephalid Broker or Lore Broker or your force discard/draw creatures such as Barbed Shocker or Abyssal Specter (there are many other Specter creatures that will work as well)
