Taigam, Master Opportunist

Clockspinning

Nexus of Fate

How it works

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