Lianne, Voice of Creation

Indestructible, Flying, Vigilance
When Lianne enters the battlefield, you may
search your deck, library, and exile zone for any
number of artifacts with total converted mana
costs 15 or less and put them onto the battlefield tapped. Artifacts you control are X/X artifact creatures, where X is their converted mana cost
plus one. Artifacts you control have
Indestructible. Whenever you cast a spell, create
an X/X artifact creature with flying, where
X is that spell's converted mana cost.
