And once again, if you companion it, it's very easy for a player to just point out it doesn't work
Just watch out for certain Exile spells like Swords to Plowshares or Vraskas Contempt that would make recasting Optimus more expensive (the Commander tax applies to both sides), or other annoying blue cards like Capture Sphere that doesnt kill him but does prevent attacking and blocking
They give you card selection, replace themselves, and naturally fill your graveyard
To make better use of the heal mechanics with reducing strength, think about Vanellope von Schweetz Sugar Rush Princess and Vanellope von Schweetz Candy Mechanic as a Shift target that does the same
The two ways around this are to either be so fast and so dominant that you overwhelm the table before anyone can mount a response an inconsistent strategy at best or you fill your deck with enough protection and recursion that you can survive long enough to exploit an opening
As you'd expect, there aren't many Fraternal Exaltations floating around now
