Azreal

Shroud, Unblockable
If Thay is on the battlefield, Azreal has no mana
cost.
When Azreal is sent to the graveyard, for the rest
of the game, Thay attacks each turn if able.
"My name is catte, I prowle the nighte
finde barrelful of sav'ry delighte
the kin of Dwarf, my wit eludes
I finde your eels, I pawe your foods."
—Azreal
