Nurture the Embers

Manashift {2}{w} (You may cast this spell for its manashift cost. If you do, it becomes white.)
Target creature gets +X/+0 until end of turn,
where X is the number of artifacts you control.
If the manashift cost was paid, target creature
gets +0/+X until end of turn instead, where X is
the number of artifacts you control.
The best fires make the best equipment.
