Background Pony #13C9
There’s the fact that the Trio were ONLY threats to Equestria because of Discord. Chrysalis was crazy and no longer had her army, and Tirek and Cozy Glow were in Tartarus. So, even if his plan didn’t go horribly wrong, the Mane Six would have essentially had to clean up a mess HE made.
And even if the Trio hadn’t turned on him, there’s still the fact that Discord planned to RUIN THE MOST IMPORTANT DAY OF TWILIGHT’S LIFE BY SENDING THE TRIO AFTER HER THE DAY OF HER CORONATION.
