1

   Prerequisites

What do I need to start this combo?
All permanents on the battlefield.
Xavier Sal does not have summoning sickness. You have a way to create a token copy of Nazgûl.

   Steps

How does this combo work?
1
Create a token copy of Nazgûl.
2
When the Nazgûl token enters the battlefield, its first ability and Intruder Alarm trigger.

Resolve the Intruder Alarm trigger, untapping all creatures.
4
Resolve the Nazgûl trigger, causing the Ring to tempt you.
5
Each Nazgûl's second ability triggers, putting that many +1/+1 counters on each Wraith you control.
6
Activate Xavier Sal's first ability by tapping it and removing a counter from a permanent you control, creating a copy of the Nazgûl token.
7
Repeat from step 2.
