4. Repeat from step 1 two additional times.
5. Activate Slogurk by removing three +1/+1 counters from it, returning it from the battlefield to your hand.
6. When Slogurk leaves the battlefield, it triggers, returning three land cards from your graveyard to your hand.
7. Cast Slogurk by paying E due to Primal Prayers.
8. When Slogurk enters, Aetherstorm Roc triggers, causing you to get E.
