Shallan, Lightweaver Radiant

Whenever this creature transforms into Shallan,
Lightwielder Radiant add {2}{w} to your mana
pool.
{3}: Create a token that is a copy of any
non-legendary creature on the battlefield, except
it also has Vanishing 3.
During your end step, if you have no untapped
lands or no creature tokens with vanishing
counters on them, transform Shallan,
Lightwielder Radiant.
