Most planes in the Planechase format hand you two unrelated effects: a passive that shapes the turn while you dwell here, and a chaos trigger that pays out when the planar die shows the chaos symbol. This one refuses the split. The passive investigates on arrival and every upkeep, a patient trickle of Clues that quietly widens your artifact count. The chaos ability then scales off exactly that count, dropping a stack of +1/+1 counters equal to every artifact you control onto a single creature (which becomes a Plant, a flavor rider that rarely matters). The two halves are gears in the same accelerating machine: investigate exists to feed the counter payoff, and the longer you linger rolling the die, the more Clues accrue and the more violent any chaos roll becomes. That structure inverts the usual patience calculus of the format. Most planes reward you for planeswalking away before the die betrays you; this one rewards you for staying, because every upkeep you survive here raises the ceiling on the next chaos trigger. What the die does stays out of your hands, the fixed constraint every plane is built around. What this one governs is how catastrophic that luck becomes when it finally lands.
