If I draw (and play) Metamorphosis while I control The Elder Sign, do I have time to put The Elder Sign on top of Metamorphosis before Metamorphosis can attach? What about the reverse order? Suppose I have Metamorphosis but no Keepers (so Metamorphosis is unattached). Can I play The Elder Sign on top of Metamorphosis?

Similarly, with the Necronomicon, do I have time to use its special power to move Metamorphosis away before it attaches itself to the book?

A: Just for the record, it’s not so much that you play the Elder Sign on top of a Creeper, as it is that you hide a Creeper under it after both are on the table. After discussing this with Andy, his ruling was that Creepers attach instantly to applicable Keepers they share the table with (in front of a given player). It doesn’t matter which order you play Metamorphosis and the Keeper; Metamorphosis would attach instantly, and the Keeper would lose its special ability before it had a chance to use it to get rid of or neutralize Metamorphosis.
