Loki, the Trickster

Haste, menace, trample
When Loki, the Trickster enters the battlefield,
you may look at target player's hand. You may
have Loki, the Trickster enter the battlefield as
a copy of any creature on the battlefield or in
that player's hand, except it gains Hatse, Menace,
and Trample.
"Birch has the greenest leaves of any shrub; Loki was
fortunate in his deceit" - Poetic Edda
