Vivid Reflection

Trolleshift (At the beginning of combat, as long as
you control 3 or more lands with activated abilities,
this card may become a 5/6 White and Blue Trolle creature with Deathtouch, Flying, and Indestructible
until end of turn.)
When you cast Vivid reflection, it becomes a copy
of target creature or planeswalker spell with an
even converted mana cost and loses Trolleshift. If
not, it enters as an enchantment instead and gains Trolleshift.
