- Set Dark Hole.
- Summon Injection Fairy Lily.
- Attack Wall of Illusion with Blue-Eyes Ultimate Dragon. Chain Emergency Provisions to Wall of Illusion's effect, and send both Spell Cards to the Graveyard. Blue-Eyes Ultimate Dragon will change over to your opponent's side of the field, as Snatch Steal is no longer on the field, but will then return to their Extra Deck because of Wall of Illusion.
- The field is now free for a direct attack using Lily's effect (for which you have enough Life points now).
Activate Dark Hole, then Chain Emergency Provisions to it and send both Dark Hole and Snatch Steal to the Graveyard. Then summon Lily and attack directly using her effect to win.
