Bloodmage, Rare, 15g5r
Mage Destruction Enduring(5)

Tower-11
Enemy Highest facility -1
The Enduring(5) seems rather paltry considering that the Destruction keyword won't trigger when playing the same card twice. If you have other Destruction cards in your hand, you're almost always going to want to play one of them next for the trigger.
That aside, an interesting card. I like the motif, reducing your own tower to cripple the enemy. Very appropriate for blood magic.
