So let's say I have a {Thassa, God of the Sea}. I've also got a {Lord of Atlantis}. Now let's say I throw a {Phantasmal Image} on Lord. Would Thassa have enough devotion?
9/22/2011 Phantasmal Image copies exactly what was printed on the original creature and nothing more (unless that creature is copying something else or is a token; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on.
So yes, there will be 5 {U} symbols in play, which turn Thassa into a creature.
