C18: If Estrid's invocation enters as a copy of animate dead, its targeting requires it to find an aura with enchant creature, instead of a creature.

It may be relevant that I put it into play with Zur the Enchanter.

Naturally as there were no enchant creature auras in any graveyard, the game froze and I had to concede.

Well, it's no longer doing that, but it is failing to enchant anything and immediately going to the graveyard.

Looks similar to #6798

At least no more frozen game. :-)
