• 2/1/2007: The spell's target is changed to Muck Drubb only if Muck Drubb is a legal target for that spell.
• 2/1/2007: If a spell targets multiple things, you can't target it with Muck Drubb's ability, even if only one of those targets is a creature or all but one of those targets has become illegal.
• 2/1/2007: If a spell has multiple targets, but it's targeting the same thing with all of them (such as Seeds of Strength targeting the same creature three times), you can target that spell with Muck Drubb's ability. In that case, you change all of those targets to Muck Drubb.
