Sending a Spell or Trap Card to the GY is a cost.
If you control your opponent's monster with "Snatch Steal" while you have "White Night Dragon" in play and your opponent attacks the equipped monster, if you send "Snatch Steal" to the GY to change the attack target no replay occurs. If the effect of "White Night Dragon" is negated by "Skill Drain" a replay does occur.
