by more specific. He probably mean which set is the pokemon from. Not just the card number. But the set. Since a lot of pokemon have different prints, allowing for different strategies with the same pokemon.
Either way your pokemon amount is still too in consistent. Example of a good one with your pokemon.
3-1-3 Crobat PLS
2 Giratina PLS
2 Sigilyph DRX
3 Deoxys PLF
With this set up. Crobat will be your main attacker, doing 40 + 60 between turns with virbank. With the addition of 3 deoxys, it will hit for 40+ 30 +60 between turns, which is pretty close to OHKOing most non Exs. Plasma Kyurem most notably. With the addition of a bangle on crobat, it then hits for 40 +30(bangle) + 30 (deoxy) + 60 between turns to ex pokemon. Unfortunately, 10 damage short of the common ex hp. You can take out one sigilyph and put in 1 more deoxys if you deem it needed. It will allow you to hit for 140 non ex and 170 on ex. But the chances of having all 4 out are kind of slim and you still cant OHKO the likes of Darkrai, especially with resistance.
Giratina works with hypnotoxic as well. Allowing it to hit for 50 + 50 + 30(bangle) + 30 (Poison) + 30 (Deoxys). Thus being able to OHKO the exs, where crobat fails to.
Sigilyph is your only non ex non plasma pokemon. Being able to be the only thing that can attack another safeguard, mirrored pokemon. Not the best, but it also can be the most annoying pokemon in your deck to attack.
Also with this set up you can use level balls and plasma balls. No ultraballs required, thus no discarding for to pay for search.
Though you have to choose between Double colorless energy (attack in 2 turns). Or plasma energy with colress machine to allow deoxys to attack as well as sort of work as DCE, but requires a lot more luck and cards. You could try both, but it probably wont work out.
