Rise of the Eldrazi

How it works

1. Cast Rise of the Eldrazi by paying its mana cost.
2. Taigam triggers, copying Rise of the Eldrazi and exiling the original Rise of the Eldrazi with four time counters on it.
3. Resolve the Rise of the Eldrazi copy, causing you to take an extra turn after this one.
4. Cast Clockspinning with buyback by paying 3, removing a time counter from Rise of the Eldrazi and returning Clockspinning to your hand.
5. Repeat step 4 one additional time.
6. Move to your next turn. At the beginning of your upkeep, Rise of the Eldrazi's suspend ability triggers, removing a time counter from it.
7. Cast Clockspinning with buyback by paying 3, removing a time counter from Rise of the Eldrazi and returning Clockspinning to your hand.
8. Rise of the Eldrazi's suspend ability triggers, causing you to cast it from exile without paying its mana cost.
9. Repeat from step 2.
