General Tips Top
Use your b on them if they get too close or too far. Use your a to space them out and hit them at the edge so that they can't attack you. simple as that. Use your ult to prevent escape or to prevent a chase, and to generally just zone them out. In a 1 v 1, just space them out, kill them. easy easy. 2 v 2, try to get far away as soon as possible, then just start shooting from afar. they'll be tempted to just attack the roam, and you can take advantage of this, easily scoring a double kill. 3 v 3, you have to play it really safe. lock down the weapon carry, and then the crystal. If they escape try yo take backs, gold mine, or kraken. Even if they intervene you can easily kill them. Use your b to dance all over the place along with your perk, win the game.
Early Game(0 - 4) Top
With the changes to the jungle, the jungle shop no longer spawns until 4 minutes in. This is a huge change, that means that either you will have to tp back to base, or not shop for 4 minutes. If you think the enemy jungler will be aggressive during this time, then you should tp immediately after taking your fronts. Don't do this unless you are confident that you can beat them. If the enemy jungler isn't very aggressive, just passively farm and try to help your lane out a lot. after about 2 heavy steels, you should literally be able to walk into lane and get a kill with a single forward barrage.
Mid Game(4 - 15) Top
You should have a significant amount of weapon power at this point, usually by 4 minuets you should have almost 2 heavy steels. You can afford to be quite aggressive at this stage, just make sure not to face check bushes. If you fell behind and the enemy jungler is invading a significant amount, this is when you can fight back. The enemy will try to take the front treant, and when this happens, attack them. Begin to run away a little bit, aggroing the minion mine. The minion mine does about as much damage as a gold mine, and is astoundingly helpful in team fights. Just with him, you can instantly shut down any invade. Look for good opportunities to take the gold mine, and push the first turret if you get 2 kills. The first turret is extremely important, as it has the best bush for ganks in my opinion, and is very easy cover for the laner. Destroying it is a huge objective loss for the enemy team.
Late Game(15 - End) Top
You should have your core items built at this point. If the enemy carry is building crits, build metal jacket, and then war treads. If not, build fountain, and then build into metal jacket. The mid to late game is where Skye really shines, and at this point, you can 2 v 3, though I strongly advise against it. Stick with your roam, get kills when you can. The kraken is a very good bait, if the enemy team has lost one person, start kraken. It will usually attract only one person, and you can melt them very fast. Your teammates can continue the kraken, and the last enemy will be too afraid to attack you. Push into base, don't get cocky, and you'll win the game.
WHY WOULD YOU USE WAR TREADS AND FOUNTAIN?! Top
Well there's a pretty simple reason. You will do RIDICULOUS damage already, building war treads and fountain basically make you adagio. You become super tanky and have really good stuff for your team too.
Why no crits? Top
I have done extensive play testing with crits as well as classic weapon, regular weapons is WAY better. Mostly because with this build you get serpent's mask. Serpent's is the most underappreciated potato. It gives you so much survivability it's ridiculous. If you do buy crits, you'll just get insta melted, and you do a lot of damage without them already.
