Obeka, Splitter of Seconds + Time Sieve + Court of Vantress

Obeka, Splitter of Seconds

Time Sieve

Court of Vantress

How it works

1. At the beginning of your upkeep, Court of Vantress triggers, creating a token copy of Time Sieve.
2. Deal combat damage using Obeka.
3. Obeka triggers, causing you to get at least four upkeep steps after this phase.
4. Repeat step 1 during each of the additional upkeep steps.
5. Activate the nontoken Time Sieve by tapping it and sacrificing five Time Sieve tokens, causing you to take an extra turn after this one.
6. Repeat each turn.
