Forced Spark

You lose 1 life. Target creature becomes a planeswalker and loses all other types and abilities. Put a number of loyalty counters on it equal to its power. It gains: "0: Create a 0/1 creature token with “When this creature dies, put a loyalty counter on target planeswalker you control. You lose
2 life."" and "-5: Draw 3 cards. You lose 3 life."

Having such power thrust upon you is not always pleasant.
