Alexa Garris, Trickster

As long as enchanted permanent has time
counters, it can't attack or block, it has no
abilities, and it can't be targeted, destroyed,
exiled, or sacrificed by opponents.
Whenever an opponent casts a noncreature spell, proliferate.
{u}{u}{s}{s}: If Alexa Garris is a creature, she
becomes an enchantment. Attach her to a target legendary nonland permanent. Put five time
counters on that permanent. If not, she becomes
a creature.
