Walk the Aeons

How it works

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