Coat of Arms gives a huge power boost to tribal decks by rewarding shared creature types across the board. Commander players love building around tribes like Elves, Goblins, Soldiers, and Slivers, and this artifact can suddenly make a board of small creatures lethal. Its symmetrical nature also adds an exciting risk–reward element when opponents share creature types. The continual release of new tribal support ensures Coat of Arms remains a tempting finisher.
