Rennala, Full Moon Queen

Reach
When Rennala, Full Moon Queen enters the battlefield, you take the initiative.
Whenever you cast your second spell each turn,
copy it. If you've completed a dungeon, copy that
spell twice instead. You may choose new targets
for the copies. (A copy of a permanent spell becomes a token.)
"Foul trespasser. Send word far and wide. Of the last
Queen of Caria, Rennala of the Full Moon. And the majesty of the night she conjureth."
