You have any number of other nonland permanents that enter the battlefield untapped, and that can collectively tap to produce enough mana to cast Cloudshift exiled by Abdel Adrian.
Steps
1Cast Cloudshift by paying its mana cost, blinking Abdel Adrian.
2Abdel Adrian leaves the battlefield, returning Skullwinder and all other cards that were exiled with it to the battlefield.
3Abdel Adrian and Skullwinder trigger.
4Resolve the Skullwinder trigger, returning Cloudshift from your graveyard to your hand.
5Holding priority, activate any number of nonland permanents you control by tapping them, adding at least enough mana to cast Cloudshift.
6Resolve the Abdel Adrian trigger, exiling Skullwinder and the mana-producing permanents until Abdel Adrian leaves the battlefield, and creating a 1/1 Soldier creature token for each permanent exiled this way.
