Arcane Bombardment + Inspiring Refrain + Jhoira's Timebug + Capture of Jingzhou + Time Walk

Arcane Bombardment

Inspiring Refrain

Jhoira's Timebug

Capture of Jingzhou

Time Walk

How it works

1. Cast Inspiring Refrain by paying 4.
2. Arcane Bombardment triggers, exiling a random instant or sorcery from your graveyard, and then casting a copy of Capture of Jingzhou and Time Walk without paying their mana costs.
3. Resolve the Capture of Jingzhou and Time Walk copies, causing you to take two extra turns after this one.
4. Resolve Inspiring Refrain, causing you to draw two cards and exile Inspiring Refrain with three time counters on it.
5. Activate Jhoira's Timebug by tapping it, removing a time counter from Inspiring Refrain.
6. Move to your first extra turn, removing a time counter from Inspiring Refrain during your upkeep.
7. Move to your second extra turn, removing a time counter from Inspiring Refrain during your upkeep.
8. Inspiring Refrain triggers, causing you to cast it from exile without paying its mana cost.
9. Repeat from step 2.

This dazzling chain reaction turns a single spell cast into a perpetual loop of extra turns and card advantage. It all kicks off when you cast Inspiring Refrain, prompting Arcane Bombardment to trigger and cast powerful free copies of Capture of Jingzhou and Time Walk from your graveyard. Meanwhile, the original Inspiring Refrain exiles itself with time counters, and Jhoira's Timebug steps in to effortlessly manipulate those counters so the suspend card comes off delay in time for your next extra turns, ready to re-trigger the entire devastating cycle anew.
