Akiri, Line-Slinger

Time Sieve

Ruthless Technomancer

Brago, King Eternal

How it works

1. Deal combat damage using Brago.
2. Brago triggers, causing you to blink Ruthless Technomancer.
3. When Ruthless Technomancer enters the battlefield, it triggers, causing you to sacrifice Akiri and create at least six Treasure tokens.
4. Activate Time Sieve by tapping it and sacrificing five Treasures, causing you to take an extra turn after this one.
5. Activate Ruthless Technomancer by paying 2 and sacrificing a Treasure, returning Akiri from your graveyard to the battlefield.
6. Repeat each turn.
