First of all, this is what spirit mirror does:
Spirit mirror 2WW Tempest Rare
During your upkeep, if there are no reflection tokens you may put a 2/2
token that counts as a reflection into play under your control.
0: Destroy Target Reflection.
Not that good of a card? try adding these cards in to make it
Donate 2U Urza's Destiny Rare
Target opponent gains control of target permanent you
Conspiracy 3BB Mercadian Masques Rare
Choose a creature type. All creatures in your library, hand and graveyard
and in play are creatures of the chosen type.
It's simple. You name reflections when you play conspiracy and then you
donate it to the opponent. Then you have a free plague wind to use as many times
as you want!
