From inside the deep mist I watch the enemy's movimentation outside the base (What, you thought I would put up all that fog without me having a way of seeing through it?). Tamer was quicker to come back than I expected, and worse, he's made it through a time-space rip... So he actually has a way to get into our defenses! 
 Suddenly they all fly away on the back of the dragon Bahamaut and fly away from the hill. 
A plan comes to my mind, and with can just outpredict our enemy, we may have a key advantage in hands. 
 "Rose, please get everybody out of here with your spells, I'm got an idea." 
As we proceed to evacuate the base I go make some preparations for the welcoming comitee, setting up explosives on all the perimeter of the hill and the castle. 
 After everything is set up I myself abandon the hill and get hold of the Masterball on my pocket, preparing my ace. 
The hill is still covered in mist, so our enemies are unaware that we moved out in their abscence, the rip opens again and... 
  BOOOOOOOM! 
Damnit! I thought they were going to invade, not blast the place up! 
 Tamer and his forces appear again just in front of me, luckily without noticing that I'm there. While I think of something to do, I hear a loud crack and than all hell breaks loose. 
 The barrier on the castle was made for attacks from the outside, not the inside. The detonation of both those missiles and our bombs was too much for it to contain. Everybody is engulfed in a storm of flames, and now I can't really see a thing while protecting myself. 
 I hear Bahamauts enraged roar from within the storm and realize that Tamers MSM is the only thing able to protect his armies now. So, time to proceed with the plan. 
 "Jirachi, I choose you!" I scream over the storm, while releasing the star shaped legend from it's pokéball. 
"Jirachi, I've been keeping my wish for this moment. I wish Tamers Master Summon Materia is deleted from existance never to return again!" 
 Jirachi begins to glow and disappears, having acomplished my wish. At the same time Bahamauts mighty roar stops suddenly, and this time for good. 
   As the burning hell released from the hill begins to fade I fly over the terrain to check out for the results of all this mess. 
  Check-mate Tamer.
