1st Budget Lost Zone (Help is welcomed.)

This is a budget lost zone deck I am planning to use for an expanded format tournament in my local game store. The Opponents I face are either using Lugia VStar or Mew Vmax with control on the field. I want advice on how to make this better. This is on standard as I cannot get my hand on older cards as its too expensive, I am building a standard deck to use in Expanded. 

The gist of this deck is lost zone but with darkrai to deal with mew vmax through darkness weakness. Yveltal can also deal

This is a budget lost zone deck I am planning to use for an expanded format tournament in my local game store. The Opponents I face are either using Lugia VStar or Mew Vmax with control on the field. I want advice on how to make this better. This is on standard as I cannot get my hand on older cards as its too expensive, I am building a standard deck to use in Expanded. 

The gist of this deck is lost zone but with darkrai to deal with mew vmax through darkness weakness. Yveltal can also deal with Mew Vmax but they're there to deal with Lugia vmax deck using special energy. Of course I can also use them to deal with Mew Vmax deck that use special double colorless energy. 

Snorlax is there to act as a tank and prevent opponent from retreating [Mew Vmax, Air balloons] Also the original snorlax that is on a lost zone deck I could not get my hands on. 

Rest of the cards are the usual lost zone deck.

Trainer wis, I have battle vip pass to get bench going, all the lost zone cards minus field [Yes lots of vacuum but the opponent run stadium deck a lot or pokemon tools.] Fantania is there in hopes that I can negate loads of the vmax dmg. 120 off a 210 attack will be 90 dmg only. Boss Order to pick off enemy retreat moons before they get too big, Marnie to shuffle,  switch cart to save units and to use comfey ability twice. [I couldn't get my hand on a scoop up] Rescue Carrier to get back units that have died. Great ball and Ultra ball to search for mons. Choice Belt to help deal with V, Vmax, Vstar. 8 darkness 2 psychic.  [8 darkness for yveltal and darkrai. will try to put it mostly on darkrai to up the dmg.]

Darkrai is the sweeper with the reduce dmg when it has a darkness energy, fantania to reduce dmg further so lugia vstar with powful energy attach dealing around 300 dmg, minus 120, minus 20, 160 [still kills sadly] but yeah any tips is much appriciated.
