Primo, the Unbounded + Breath of Fury + Barbarian Class

Primo, the Unbounded

Breath of Fury

Barbarian Class

How it works

1. Deal combat damage to an opponent using the creature that has Breath of Fury attached, triggering Breath of Fury and Primo.
2. Resolve the Primo trigger, creating a 0/0 Fractal creature token that enters with a number of +1/+1 counters on it equal to the damage dealt.
3. Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to and attach it to the Fractal token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
4. Repeat each combat phase.

By enchanting a creature with Breath of Fury and dealing combat damage to an opponent, you set off a devastating looping engine fueled by Primo, the Unbounded. Each successful strike triggers Primo to generate a massive Fractal token matching the damage dealt, which Breath of Fury then seamlessly jumps to as it sacrifices your previous attacker, untapping your entire board and granting you an endless chain of extra combat phases. Meanwhile, Barbarian Class provides haste at level 3 so your newly spawned tokens can immediately charge into battle without summoning sickness, cementing a relentless loop of combat and sacrifices.
