Yennett, Cryptic Sovereign + Liliana Vess + Venser, the Sojourner + Nexus of Fate

Yennett, Cryptic Sovereign

Liliana Vess

Venser, the Sojourner

Nexus of Fate

How it works

1. Activate Liliana's second loyalty ability by removing two loyalty counters from it, searching your library for Nexus of Fate, shuffling your library and putting Nexus of Fate on top of your library.
2. Activate Venser's first loyalty ability by putting two loyalty counters on it, exiling Liliana until your end step.
3. Proceed to your combat phase, and declare Yennett as an attacker.
4. Yennett triggers, revealing Nexus of Fate from the top of your library and causing you to cast it without paying its mana cost.
5. Resolve Nexus of Fate, getting an extra turn after this one and shuffling it into your library.
6. At the beginning of your end step, Liliana returns from exile to the battlefield.
7. Repeat each turn.
