Marchesa, the Black Rose + Time Sieve + Myr Battlesphere

Marchesa, the Black Rose

Time Sieve

Myr Battlesphere

How it works

1. Declare Myr Battlesphere as an attacker, attacking the opponent with the most life or tied for the most life.
2. Myr Battlesphere's dethrone ability triggers, putting a +1/+1 counter on it.
3. Activate Time Sieve by tapping it, sacrificing Myr Battlesphere and four other artifacts you control.
4. When Myr Battlesphere dies, Marchesa's second ability triggers, causing you to return Myr Battlesphere from your graveyard to the battlefield at the beginning of your end step.
5. Resolve the Time Sieve ability, causing you to take an extra turn after this one.
6. At the beginning of your end step, Marchesa triggers, causing you to return Myr Battlesphere from your graveyard to the battlefield.
7. When Myr Battlesphere enters the battlefield, it triggers, creating four 1/1 Myr artifact creature tokens.
8. Repeat each turn.
