Supersolid Light

When Supersolid Light enters, entangle the top card
of your library.
At the beginning of your upkeep, if you control both an artifact and an entangled card, choose one —
• Target nonland permanent phases out.
• Scry 1, then gain 2 life.
• Until end of turn, Supersolid Light becomes a 2/2 Elemental creature with flying and lifelink.

"Its existence is a hypothesis… until it touches you."
