A good way is to involve the fans of both. Have references that only fans of MLP or Minecraft would understand. For MLP, it could be a reference to a particular episode or a little - known pony character. In Minecraft, it could be about a rare item or a secret location. The writer should also build up the tension and conflict. Maybe there's a race against time to stop a Minecraft boss from destroying the MLP world that the ponies have brought into Minecraft. This would keep the readers on the edge of their seats and make for an engaging fanfiction.
To make it engaging, the writer can focus on the contrast between the two worlds. MLP is a colorful, magical place, while Minecraft is more blocky and based on survival and creation. The ponies' magic could interact with Minecraft's mechanics in interesting ways. For example, Rainbow Dash's speed could be used to quickly travel across the Minecraft map. Also, including some humor would be great. Like when the ponies first see a creeper and think it's some kind of strange new monster from their world. They could try to befriend it in their typical MLP way, which would lead to some comical situations.
