Does this mean bricks-only, or does it work on mixed-cost cards that include bricks? I think the latter would prove too much. If it means bricks-only, it should be adjusted for clarity.

Brick only, I'll update it now

Initially i wanted it to target wall+ tower+ cards

cool... same as steam golem: good idea, nice new card :-)

P.S: I can imagine, why you prefered "bricks-only" to wall/tower+ ;-)
