Call for Martyr

Create a 4/4 white Order creature token
with haste and "If able, this creature must be
blocked."

Destroy a permanent an enemy controls with
X total mana cost. If that destroyed
permanent has souls to the call, this card
perpetually gains "Flashback {x}{4}{w}
(You may cast this card from your graveyard
for its flashback cost. Then exile it.)".
