Its your boy Zach Lesage here, and Im excited to help you start your Pokemon TCG journey
MST is good for sniping Emptiness, but if I wanted to get rid of other traps, most of which are chainable this format, I'd rather run Wiretap or Trap Stun
You could either play the deck at 50 cards to preserve its current state with a little less consistency, or you would cut Dark Hole and/or a Rescue Rabbit to play the deck at 45 cards
However, it Banishes the Monster instead of destroying it, which makes it much harder to get the affected Monster back onto the Field
Keep that in mind as you continue your card grading adventure
Other awesome as well as playable Alpha highlights include a Nevinyrral's Disk (EX), Chaos Orb (NM), Mana Vault (EX), Demonic Tutor (NM) as well as a bunch of Swords to Plowshares (NM) and Lightning Bolts (EX)
