One major upside is that many many , even experienced players play incorrectly against this. I call it the standstill effect. We recently saw it in standard with perilous vault. The aggressive player has insufficient pressure on the board and doesn't want to over extend into the board wipe. This gives the control player time to get the upper hand and they don't even have to do anything. It also plays really well with man lands.
Still a stone cold staple for me. 'The button' has had the magical ability to turn any mish mash of colors into a control deck. I have actually found that the prevalence of more and better enchantments has made this more valuable. It has never been a top pick for traditional azorious control as they just usually want the wrath. But the black control decks.... Mono, Rakdos, Dimir, Grixis are all looking for ways to take out nasty enchantments (sometimes their own). Plus black is in the driver's seat when things go to the graveyard.
Oh and true name nemesis
