You are right about the sacrifice in damage output. Most importantly, you loose that output against the powerful non-EX attackers we have in the format, as you mentioned. However, I would like to point out that not playing LaserBank makes TDK a spacious deck with more room of consistency cards. For example, you run 4 Lasers, 2 Virbanks and 2 Bangles. That is 8 Cards were a deck that runs only bangle is only running 3-4. That means they can run four or five more cards to make their deck run more consistently than yours. If you run 4 Kyurem, 4 Colress Machine, 4 Skyla and 13 energies you are going to get Turn 1 Frost Spear more often that someone running 3 Kyurem, 3 Colress Marchine, 3 Skyla and 12 energies. You are also more likely to have a Deoxys or two on the bench turn 1 if you run 4 instead of 3. I'm not saying your build isn't powerful or the right way to build it, but it is worth testing the deck without lasers when you see the benefits you can gain in consistency. I see a lot of people talking about how 4 Colress Machines is to many because of late game or you don't need 4 Deoxys, but this deck is all about overwhelming the opponent as quickly as possible. Its not always about how many you need, but how often you want to see a particular card. Do you want to see Kyurem, Colress Machine and Deoxys turn one? Why not run four of them then? I like Bangle w/o LaserBank for these reasons. The build I'm testing now is even more consistent than my build from last format at getting those turn one Frost Spears. Frost Spears that can 2HKO EXs now that we have Silver Bangle.
