Human—Time Lord Meta-Crisis
A Phenomenon exists for exactly one heartbeat: the planar die walks you onto it, you resolve its effect once, then planeswalk immediately away. That transience is the design constraint everything here answers to. A Plane sits in the command zone bending the game's rules while it stays face up, accruing value across turns; a Phenomenon has no such runway, so its effect has to land hard in a single beat and then vanish. What this one hands out is a symmetric clone party: every player copies a creature they control, stripped of its legendary status so the token can coexist with the original. Choosing a second creature is pure upside rather than a cost: the token simply arrives with +1/+1 counters equal to that second creature's power, so a player holding a heavy hitter in reserve can inflate the copy into a much larger body while still keeping the original on board. The whole table gets the same offer at once, which is the point. This is a group effect wearing crossover flavor, the kind of one-shot spectacle Planechase was built to produce: no repeatable engine, no board state to defend, just a moment of shared chaos dealt out equally to everyone in the encounter before the die sends the game somewhere else.
