3* Thanos Court of Death VS Protection Tile

Question:
Luke Cage had a 150 strength protection tile on the board when Thanos fired Court of Death. It is written to deal 168 dmg to his allies. And my allies took 168 damage. Shouldn’t the protection tile have negated 150 of that, lowering the dealt dmg to 18?

No. Friendly protect tiles only counter damage from enemies – not from allies. But at the same time, self damage will not be enhanced by enemy strike tiles, either.
