@Otaku I don't think Vespiquen is viable without battle compressor, especially with the rise in popularity of mega's and EX pokemon with Fighting fury, as worlds was proof of nm and Vespiqen struggling to get knockouts on the beefier Pokemon.
Vespiquen is very viable in next format because of forest of giant plants, free retreat and DCE. It needs to be played differently because the meta is slower, but it can still hit the high 150 to 180 mark for end game knockouts. It is not the lead attacker anymore. It works as a solid backup attacker with one turn evolution's. The card is dangerous. It plays more like Zorark and mops up. Also, it can still be paired with unown which can offer just enough power for a prize exchange war. I take two. You take one. Lysandre is a harder play. In the next meta, free retreat is a big deal. Not only that, but I still haven't seen a really good deck list where only 4 dce in a deck list can survive in this format.
I think those days of power hitting off the 4 dce deck list are getting fazed out a bit. Trainers will adjust the cards to variant strategies, but the cards are not worthless in the format, just the first turn power hit strategy is evolving to something more subtle.
