Destiny Warrior Spider
i can easily
Typhlosion: Flare Blitz is a good hard hitter but it requires good speed,high power and to hit more importantly. Eruption i would use Whenever possible like at the Start of battle because it gains atk from higher HP.Solar Beam is risky because of the wait but it does hit hard too.FLamethrower you cant go wrong with.
Leafeon: Leaf BLade is a Classic move it hits hard and it has high crit no problem there.Dig is also a good choice but its pointless unless youve got the speed for it.Synthesis is good but regaining health isnt very useful but its your pkmn its your choice.Magical Leaf cant miss, does moderate damage its a hit and miss with that move.
Altaria: Dragon Pulse does good damage and it can flinch no problems there but speed.Perish Song its a good move to use when you have more pkmn than your opponent other than that its useless.Sky Attack it hits hard but its like fly but it does more damage and misses more often if i remember right.Draco Meteor i wouldnt use this very often id only use it when i was in a bad situation given the Sacrifice of Spec.atk and its doesnt hit very hard.
Empoleon: Surf is a good one hits heavy it has full accuracy and it can attack everything on the field.Hydro Pump also a Classic but misses more than it does damage.Drill Peck its a great attack if your fighting a grass and or a fighting type overall good moveset.
Gallade: Close Combat is a must have for a Gallade even though the sacrifice of Def points because of its power... and it hits harder from gallades enourmas atk power.Psycho Cut is good from its moderate power and its crit rate but other than that is a maybe. Psychic and Focus Blast they both hit hard... BUT! they dont utilize Gallades Great atk power.
Umbreon: Moonlight its a healing move not very good but again its your pick.Dark Pulse is a good one but it has very little Super effectivness.Faint attack same as Dark Pulse but it hits everytime and is weaker.Last Resort its a good attack...that is if you want to faint your pkmn in the process. but it does hit pretty hard.
(your team is pretty good but its could be a bit better)
This is me responding to your advice.
About the HP restoring moves- I often see moves like this coming in handy for tight spots. When I know a supereffective move is going to come or when I am waiting for the enemy to attack with a move such as fly, bounce, or dig, I often use these, especially on Umbreon.
Perish Song- I like using this move the turn before it becomes evident that Altaria is going to faint, I use this. However, if Altaria does not faint, I switch him out the turn before he does faint from Perish Song.
However, I love your advice on Gallade. I never realized what you told me, so I have decided that I will change the moves before I actually get them. I will try to find a replacement for Psychic, but I want to keep Focus Blast.
