"Another target creature" is the standard template rather than "target other creature".
The name Resurrection is taken.
Hee. Fun idea. Unfortunately has rules issues with the way the combat step is skipped if no attackers are declared, although it has slightly less such issues than most such cards (the creature will still come back, and be tapped, but if no other attackers are declared, the combat step will end immediately).
Of course, you could propose to amend that rule so that combat proceeds if there are any attacking creatures, which would be eminently sensible.
Ha! Fantastic fun. Awesome with Doran, the Siege Tower and pretty good with Angelic Chorus; not so good against Banewasp Affliction or Phthisis :)
It looks like you may not have assigned rarities yet, but this shouldn't be common. Kami of Old Stone was uncommon, which felt right. Indomitable Ancients was rare, which felt slightly dubious, but at least may have been right.
