Ingenious Measuretaking

Funproof target spell or permanent. (Change
the text of that spell or permanent by replacing
all possibilities for creative misuse with standardized, fail-safe phrasing. For example, "target player" becomes "target opponent",
"in any order" becomes "in a random order",
and Oblivion Ring becomes Banishing Light.
We can't have pesky outside-the-box thinking ruining the game.)
