I think one of the lasers in any deck could be worth it, but to say it would be worth 3-4 in my mind is a little outlandish.
Again, this is just my opinion. I have definitely been wrong before.
I will agree about the ninetails though. That deck could see some competitive play and may do fairly well
A quick bit of explanation to avoid me sounding as rude or weird as I fear: I began quoting you where I did for emphasis, especially as this thread was started by someone who missed a month of serious play and news... and this isn't just a back and forth between the two of us, but really two individuals that are part of a larger group discussion.
I don't think every deck needs to max out
Hypnotoxic Laser and/or
Virbank City Gym, and I have been trying to remind many to "do the math" and realize that it isn't something you use every turn. At the same time, I believe it will be widely played as at least a TecH card, and running two of it and two
Virbank City Gym may be a viable model. That isn't to say maxing it out won't work for some decks (possibly most), but I think there is some flexibility. If it is as popular as anticipated, then running one copy or even no copies of
Virbank City Gym may be acceptable, because your opponent will often supply it for you.
A single
Hypnotoxic Laser (outside of Weakness) yields the same damage bonus as a
PlusPower, plus a 50% chance of inflicting Sleep, which means by the time your opponent's turn starts there is I believe a 25% chance of the opponent's Active Pokémon being Asleep. Lousy as an attack, but pretty nice for an Item. If
Virbank City Gym is used, the two cards result in the same net damage counter increase as three copies of
PlusPower (again barring Weakness). In either case, they turn near KOs into KOs, saving an attack... when people do the math correctly.
