It was one of my picks for the World Shaper deck upgrades, especially with [[Szarel, Genesis Shepherd]] in the mix
The first two abilities just arent great in Commander, but the emblem is scary enough that people have to attack this Bant card down anyway
Each different gem corresponds to a different color of mana, so if a player had a rainbow deck with all five, they could unleash an unpredictable, and powerful, strategy of their choice
I happen to like the card for its aggressive Voltron slant
+1/+1, trample, and haste all on one piece of gear means your threat hits harder, gets through blockers, and starts to deal damage right away, so it snowballs way too fast when youre already chaining spells
