While that is surely strong, it might be the Warmasters triggered ability that is truly special, as you get to create a 1/1 Elf Warrior token (once per turn) whenever an Elf joins your side of the battlefield
I am running these over cheaper options like Sign in Blood since they'll draw more cards
The deck features enter the battlefield triggers including graveyard hate (Angel of Finality), Bolster (Anafenza), artifact/enchantment removal (Angel of the Ruins), creature tokens (Blade Splicer, Emeria Angel, Regal Caracal), flicker (Charming Prince, Restoration Angel, Flickerwisp), reanimate (Emeria Shepherd, Karmic Guide, Sun Titan), venture (Nadaar, Radiant Solar), fetch (Solemn Simulacrum, Ambitious Farmhand), creature removal, life gain, and much much more
If you're playing with DFCs and opaque card sleeves, you're good
