Help deciding the Delta-Team

I usually like making Theme Teams, mainly based on the regions, and at Insurgence, I decided to make a Full Delta Team, but i can´t decide about the last 2 slots, so i´d really appreciate any feedback and recommendations for the team.
But as I said, I will only use Delta Pokes

Here are the ones that i have planned to have so far:

Delta Gallade

For this one have 2 options

If you’re gonna PvP, beware against entry hazards as you have nothing to remove them. Stealth Rock + Spikes + priority attack will obliterate your team.

But, if you insist:

  • If you gonna have defensive DBlastoise, go with Careful + full SpD as Bulk Up increases Def anyway. You may want to equip Lum Berry or Sitrus Berry as its only recovery method.
  • For DVenusaur, maybe it is better to be physically defensive with Calm Mind because its speed is not that high and it also has Moonlight. Another option for DVenusaur is to be Leech Seed staller combined with Toxic Spikes from DLuxray.
  • Special attacker DFroslass with Choice Scarf is very dangerous to any non scarfed Pokemon that doesn’t resist Eruption. If Choice Scarf is equipped, Wildfire can be changed into Dazzling Gleam for another super effective coverage.
