I am a senior division player new to the tcg game and rules. Over the past year I've observed other decks being played and attending pre-releases. This is the first deck I've ever made so please read over what's in it and leave feedback on how I could improve it. 
Pokemon
My strategy is to win all six prize cards by poisoning my opponent's Pokemon.
Toxicroak EX has the move Triple poison, which puts 3 damage counters instead of one for poison. Combined with Virbank City Gym, my opponent is taking 50 damage between turns.
Similarly, Crobat has the move Ultra-Toxic Fang with does 40 damage and puts 4 damage counters instead of one for poison. With Virbank City Gym, that's 60 damage between turns. Also with a Muscle Band, that's a OHKO for all EX (not including megas) if they can't retreat.
Since retreating would make the poison go away, I've included Dragalge which has the ability Poison Barrier, which prevents my opponent's poisoned Pokemon from retreating.
Virizion EX would be a problem so I've included Lysandre to try to knockout Virizion.
Lysandre and Startling Megaphones help with Yveltal/Garbodor decks.
Mr.Mime is to ensure Dragalge isn't hit.
The rest of the cards are self explanatory.
