Spidey - Yep. If someone pays WR to cast it, the enchanted creature gains first strike and haste. If they pay 1B, it gets 'Sac: Opponent discards'. If they pay GU, it gets trample and flying. Note that you don't HAVE to use two colors...you can use one mana of any color and one colorless. You just benefit if you do. Duke - No kidding? I'll have a look.
