Calm Before the Storm — Whenever Lucas, the Serene Defender is dealt damage, you may exile him until your next end step. If you do, prevent all damage that would be dealt to Lucas this turn and to any other creatures you control.
Self-Defense Stance — Whenever an opponent attacks you or one of your planeswalkers, you may have Lucas, the Serene Defender block that creature. If you do, Lucas deals damage equal to his power to that creature, then gain life equal to the damage dealt.
