Gideon\'s Reclamation

Black creatures can't attack unless their controller sacrifices a land of their choice for each black creature they control that's attacking. (This cost is paid as attackers are declared.)

+2: During target opponent's next turn, creatures that player controls attack Gideon Jura if able. −2: Destroy target tapped creature. 0: Until end of turn, Gideon Jura becomes a 6/6 Human Soldier creature that's still a planeswalker. Prevent all damage that would be dealt to him this turn.
