To be fair, the absolute limits of magic in MLP have never really been established. In fact they've actually been broken on occasion ||(Twilight telling Trixie certain spells are impossible in Magic Duel, and then Twilight literally performing a duplication spell in "Fame and Misfortune." Also Twilight being unable to change Gender, yet capable of giving gills and fins to a pirate, turning into a different species, and changing living beings into inanimate objects and vice versa)||
I will say though, Equestrian magic does also borderline on warping reality. However, one thing to consider is whether death is permanent to a draconequus. We know that if Discord so much as acts against his nature, he will fades from reality, but he immediately started reforming from secondhand acts of "disorder"
Since magic can channel ideas, maybe we can ty this to the conceptual magic explanation to theorize how to physically kill him. Celestia and Luna were able to defeat him without the Elements of Harmony in certain timelines.
