Stealth Rock and Poison Heal are illegal on Gliscor. It appears to me that Tyranitar is good at it considering that you use Excadrill:
-Stealth Rock
-Crunch
-Fire Blast
-Superpower/Stone Edge/Ice Beam
Nature: Sassy
EVs: 252 HP/180 SAtk/76 SDef
Item: Leftovers
Ability: Sandstream

Venusaur works best in Sun teams, so it's best to replace it with something else like Reuniclus:
-Calm Mind
-Psychic/Psyshock
-Focus Blast
-Recover
Nature: Bold
EVs: 252 HP/252 Def/4 SAtk
Item: Life Orb
Ability: Magic Guard

As for Gliscor, use this instead:
-Substitute
-Protect
-Earthquake
-Toxic/Taunt/Ice Fang
Nature: Impish
EVs: 252 HP/184 Def/72 Spe
Item: Toxic Orb
Ability: Poison Heal

I'll provide suggestions for your last 2 slots later; if not, someone else can do it.
