2. 2Holding priority, activate Lithoform Engine's first ability by paying and tapping it, copying Mishra's trigger.
3. 3Resolve the first Mishra trigger, creating a 4/4 artifact creature token copy of Gonti's Aether Heart named Mishra's Warform.
4. 4When Mishra's Warform enters the battlefield, it and Gonti's Aether Heart trigger, causing you to get four energy counters.
5. 5Resolve the second Mishra trigger from step 1, creating a 4/4 artifact creature token copy of Gonti's Aether Heart named Mishra's Warform.
6. 6Put either Mishra's Warform into your graveyard due to the legend rule.
7. 7When the second Mishra's Warform enters the battlefield, both Mishra's Warforms and Gonti's Aether Heart trigger, causing you to get six energy counters.
