Possessed Skaab

Time Walk

How it works

1. Cast Time Walk by paying its mana cost.
2. Kykar triggers, exiling Possessed Skaab.
3. Resolve Time Walk, causing you to take an extra turn after this one.
4. At the beginning of your end step, Kykar triggers, returning Possessed Skaab from exile to the battlefield.
5. When Possessed Skaab enters, it triggers, returning Time Walk from your graveyard to your hand.
6. Repeat each turn.
