Actually unlike the other characters who have supposedly died, Makarov was actually and truly dead(this was confirmed by all of the cast members present at his final moments). If you recall, resurrection magic is completely impossible in this series.

The reason why he was brought back was because of the use of the One Magic, which as the source of all magic can pretty much do anything it wants, including revive the dead and completely overturn an actual gods power and authority.

Compared to the One Magic, Fairy Heart is a joke.....
