I thought about getting another Mysterious Triangle, only having 1 Detonator Circle, Getting another Alien Warrior and Alien Ammonite, Taking 1 alien dog and 1 alien hunter out and getting alien mother.
Again, tell me what you think.

Is warrior the 1800 attacker? Cuz if so you want lots of him.
A good thing to remember is reptile support cards work well too. Such as molting escape damage equal reptile.

Also I would look at waboku works great with one of your cards. Can you guess which?
Overal looks like a basic alien deck to me.

Put Alien Warrior in 3s, it's great as a beatstick and for A-counters.
Alien Shocktrooper's only purpose is as a beatstick and can be easily killed by backrow cards, so you should take it out.
I think you should take out Interplanetary invaders out as drawing the right kind of cards for it to gain control and not lose LP is situational.
Max out Alien ammonite, it's a great Tuner for Aliens.
I think you shoud take out one Flying Saucer, as it could become dead draw if you get it at a bad time.
Alien Infiltrator seems useless so take that out.
Max out on Alien Greys, they are great for A-Counter distribution and great draw power.
I think you should take out Alien Incubator because the chances of your opponent destroying it are slim.
Orbital Bombardment isn't very good imo because killing a monster just to kill one of your opponent's backrows aren't very worth it, but I think you should put it in 1 for now.
Take Crop Circles out, it really situational imo.
I also think you should take out Detonator Circle A because the chances of getting your opponent with an A-counter aren't very high, plus the 1k DMG isn't very worthwhile.

I think you should add some staples, like Mirror force, Monster Reborn, or Dark Hole.

Overall, it seems inconsistent.

Thanks for the help. I found some of my aliens that I had lost, so I can reform the deck, though I don't have many Alien Warriors [Only 1.] So I'll see what I can do about getting one or two,

Dally:
I only have about one or two Alien Warriors.
I have found Alien Shocktrooper to be somewhat useful at times, so I might keep in just one.
With Interplanetary Invader, if I had a card like Spirit Barrier [I think that's the name of it.] Then it would be fine.
As with Alien Warrior, I only have one.
I probably will, but I will keep it in until I can add better cards to the deck.
I only have one Alien Grey.
I may, though if I had something to destroy it, like heavy storm or such. [Heavy Storm would be better, if I had little to no other spell/trap cards on the field.
I will probably take it out, since I never really saw it as a great card.
I might keep in one Crop Circles, since it has been of great use to me.
And once again, I do not have a card to replace it at the moment.

Again, thank you for the feedback.
