Greninja is used as my lead to set up spikes and deal whatever damage it can with it's speed, Trevenant is my smeargle spore counter and spin blocker also acts as a great physical wall and decent special wall/tank. Goodra is my special wall setting up rain dance to power up muddy water and to prevent sleep when I rest takes hits like a champ. Talonflame is my revenge killer with a bulky swords dance set goes in for priority brave birds to pick off the weak. Excadrill is one of my physical sweepers and rapid spinner. And Mega lucario for special sweepings Please rate my team thnxs!

Excellent choice of pokemon though goodra isn't the best dragon type you could go for maybe a haxorus or a garchomp but that is my opinion also you might want to consider a fairy type eg. Sylveon or florges-which has high sp. def and the STAB moonblast

very good but rest? sorry but I dont like this attack

You have a very good strategy, but I'm going to point out a few things you could change.
(First, I'm assuming by Atk you mean Special Attack with your Lucario, right?)

Anyway, you probably will want to swap Trevenant's Lum Berry for a Sitrus Berry.  This will help it survive longer and will be much move useful than healing status problems.

Your Greninja strategy has some downfalls.  Giving it a Focus Sash and letting it use Spikes isn't taking advantage of its fast, offensive potential.  I'd suggest a different move like Dark Pulse or something similar, and you may want to switch Hydro Pump with Scald or Surf, as they have more PP and accuracy.
If you want to set up Spikes at the start, consider a Pokémon like Forretress.  It doesn't even need a Focus Sash with its ability Sturdy and can also set up Toxic Spikes and Stealth Rock (egg moves).

Great team overall!
