2. When Lagrella enters the battlefield, it and Preston triggers.
3. Resolve the Lagrella trigger, exiling Sun Titan until Lagrella leaves the battlefield.
4. Resolve the Preston trigger, creating a token copy of Lagrella that is a 0/1 Illusion.
5. Put the nontoken Lagrella into your graveyard due to the legend rule.
6. If Lagrella is your commander, choose not to return it to the command zone from your graveyard.
7. When Lagrella leaves the battlefield, Sun Titan is returned to the battlefield from exile.
8. Sun Titan, Lagrella and Preston each trigger.
9. Resolve the Preston trigger, creating a token copy of Sun Titan that is a 0/1 Illusion.
10. When the Sun Titan token enters the battlefield, it triggers, choosing to return nothing to the battlefield.
11. Resolve the Lagrella trigger, putting two +1/+1 counters on the nontoken Sun Titan.
12. Resolve the Sun Titan trigger from step 8, returning Lagrella from your graveyard to the battlefield.
13. Repeat from step 2.
