The Drum, Mining Facility

Planechase geography tends to hand you a static effect and let you sit on it; this one is loud and immediate, tying its payoff directly to the act of rolling the planar die. Every roll turns your board into a hasty aggressor, which means the plane rewards the same die-spam that most Planechase games already incentivize: chaos symbols and Planeswalk symbols both live on that die, so the more you roll to fish for one, the more free anthem-plus-haste triggers you bank along the way. The tension is in the second line. Rolling toward a chaos result is normally the fun-generating engine of the format, but here landing on chaos ends the turn outright, wiping the stack and shutting down your own attack step before the +1/+1 and haste can matter. So the plane sets up a small internal gamble: each roll pumps your team, but the roll that finally hits chaos slams the door on the turn you were building toward. It is a rare piece of Planechase design where the die is not just a random-outcome generator bolted onto a normal game but the actual axis the plane is built around, punishing the greedy roll while paying off the disciplined one.
