: Phase
2 random immaterial creatures or weapons, plus Immortal, ignore shields for one turn.
So, the Immortal that uses this ability gains momentum, then, 3 out of all the immaterial cards you have on the field (including the Immortal that uses this ability) gains momentum, so if you have 6 immortals and 17 non-immortal immaterial creatures, and each immortal uses "phase", then you can have anywhere from 6 to 18, out of 23, momentum creatures each turn.
