Deal combat damage using Hoard Hauler.
Hoard Hauler triggers, creating at least five Treasure artifact tokens.
Activate five Treasures by tapping and sacrificing them, adding .
Activate Najeela by paying , untapping all attacking creatures, giving them trample, lifelink and haste, and gaining an additional combat phase after this one.
Repeat each combat phase.
If the opponent controls eight or more artifacts, this combo nets infinite Treasure tokens.
This delightful loop turns an opponent's heavy treasure trove against them by pairing Najeela, the Blade-Blossom with Hoard Hauler to fuel infinite combat steps. As Hoard Hauler barrels into combat with its native trample, it cashes in on an opponent's artifact-heavy board to generate a windfall of Treasure tokens upon dealing combat damage. Those very same Treasures provide the exact five-color mana investment needed to activate Najeela, the Blade-Blossom's activated ability, which untaps your attackers and grants an additional combat phase. Meanwhile, Najeela, the Blade-Blossom's own triggered ability populates the board with attacking Warrior tokens along the way, cementing a relentless chain of assaults that can overwhelm the table and net infinite Treasures if the opponent controls enough artifacts.
