How it works
Cast Ghalta by paying 5.
When Ghalta enters the battlefield, it, Cadric and Cloudstone Curio trigger.
Resolve the Cloudstone Curio trigger, returning Priest of Urabrask to your hand if its on the battlefield, or returning nothing to your hand otherwise.
Resolve the Ghalta trigger, putting Priest of Urabrask onto the battlefield from your hand.
When Priest of Urabrask enters the battlefield, it and Cloudstone Curio trigger.
Resolve the Priest of Urabrask trigger, adding .
Resolve the Cloudstone Curio trigger, returning Ghalta to your hand from the battlefield.
Resolve the Cadric trigger from step 2, causing you to pay 1 to create a token copy of Ghalta with haste.
When the Ghalta token enters the battlefield, it and Cloudstone Curio trigger.
Resolve the Cloudstone Curio trigger, returning nothing to your hand from the battlefield.
Resolve the Ghalta token's trigger, putting Ghalta onto the battlefield from your hand.
Repeat from step 2.
This explosive loop uses Ghalta, Stampede Tyrant's massive entrance to drop Priest of Urabrask, whose red mana generation fuels Cadric, Soul Kindler's ability to repeatedly copy Ghalta without worrying about the legend rule. Meanwhile, Cloudstone Curio serves as the mechanical glue of the engine, bouncing your heavy-hitters back to your hand whenever a new permanent arrives so you can recast and redeploy them indefinitely. The result is an unstoppable chain reaction that floods your board with hasty token copies while generating infinite mana and enter-the-battlefield triggers.
