A quick check showed that while more conditional,
Duergar Hedge-Mage is also optional when it's red side is available.
But yeah, I feel like this card was needed for completeness sake when compared to stuff like what some other colors have, such as
War Priest of Thune and
Reclamation Sage.
I feel like Irreverent Revelers may want to go into some cubes in particular, where it is good at avoiding being a completely dead card when artifacts aren't around while also not forcing you to destroy your own artifacts, but still allowing you to if you need their destruction triggers or to put them in the graveyard or something. There are of course other options in red for that kind of thing, like
Abrade, but having more options is always good for larger cubes or to adjust power levels of the cube.
