Sophie, Mirror Mage

Flash, Ward {2}
When Sophie enters, create a token that's a copy of
up to {x} target permanents you control.

Whenever a non-token creature, enchantment, artifact or land enters under your control, you may pay {3}. If you do, copy it.

Looking at her reflection, she willed it to move. And
it did, moving towards her through the glass of the mirror.
