- Cast Etali by paying {5}{R}{R}.

- Holding priority, activate Phyrexian Altar by sacrificing Etali, adding {B}.
- Activate Haunted Crossroads by paying {B}, putting Etali on top of your library from your graveyard.
- Resolve the Etali trigger from step 2, causing you to exile cards from each player's library until you exile a nonland card, with you exiling Etali from your library, and cast Etali and any other nonland cards exiled this way without paying their mana costs.
