Magical Hack

If you change the text of a spell which is to become a permanent, the permanent will retain the text change until the effect wears off.

Can target a card with no appropriate words on it, or even one with no words at all.

You can’t change proper nouns (i.e. card names) such as “Island Fish Jasconius”.

Alters all occurrences of the chosen word in the text box and the type line of the given card.

Changing the text of a spell will not allow you to change the targets of the spell because the targets were chosen when the spell was cast. The text change will (probably) cause it to be countered since the targets will be illegal.
