Okay, so like Ambush was Empoleon/Lucario. Two different types made it hard for energy, and stuff, so here is a mono-Ambush using the new Flygon from SW.
4 Trapinch SW
3 Vibrava SW
2 Flygon SW
1 Flygon ex d (maybe 2)
4 Riolu DP
3 Lucario DP
1 Lucario lv.X MT
1 Holon Castform (1/9 chance of starting with it)
TOTAL: 19
4 Multi Energy
4 DRE
8 Fighting Energy
TOTAL: 16
3 Roseanne's Research
4 Castaway
4 Bebe's Search
2 Steven's Advice
2 Copycat
1 Scott
3 Rare Candy
2 Night Maintenance
2 Lake Boundary
2 Strength Charm
TOTAL: 25
Vibrava for just (F) can spread 10 damage on all the opponent's pokemon. There isn't any sniping, but you do have Lucario that can also spread damage while doing 40 damage. Then you have Flygon ex d that can do 80 and 10 to anything with damage on it and then also 10 to basics in between turns. I could see someone running 2 Flygon ex d and just 1 Flygon SW. Lake Boundary is to take advantage of the weaknesses. Flygon ex d with Lake Boundary in play can OHKO many psychic threats (that are weak to psychic), helping Lucario's weakness. Roseanne's Research is nice when played with Castform. Grab a basic energy and a Holon's Castform. Strength Charm for extra damage, or they could be Cessation Crystals too I guess.
Just an idea that popped into my head yesterday. Feel free to abuse it and do well with it if you can.
