How to play
General
Your first rush is Redemption.
Your second rush can be Locket of the Iron Solari (vs AoE), Moonstone Renewer (sustain).
Also, Echoes of Helia is pretty good because you can proc it consistently with Font of Life (slow/cc).
Rush second Locket if your team already doing teamfights or when an enemy team has champions with super aoe damage (example: like Fiddle's ult). Otherwise, get Moonstone Renewer #2. The third item should be whatever you did not buy - Locket of the Iron Solari or Moonstone Renewer. That's your core.
Another decent item if you have carry/strong bruiser/strong tank is Knight's Vow.
Try to use summoner spell Heal on cooldown. With Moonstone Renewer, ideally there should be at least two people for maximum healing effect.
Later in the game, for maximum support - you can sell boots for sixth item.
You can get items like Ardent Censer (some auto attackers needed) or Staff of Flowing Water. It will be triggered often enough that it will be worth.
Interesting item is Cryptbloom. If you want to go full healing, you can get it like #4+ item.
Runes
Guardian is important rune. It is going to provide tons of shielding. Remember that you need to be close to your allies to proc it.
You can also manipulate it - for example, you can stick to one ally, or avoid some spells that's gonna only waste it.
You will be triggering Font of Life effect, which will heal your allies. It also chains off Moonstone Renewer!
Font of Life total healing is not properly calculated in a post-game lobby. Value is bigger in the game vs. what's displayed in statistics. You heal more!
Another important rule is Cosmic Insight, it reduces cooldown for your active items (so more heals/shielding) and Heal summoner spell.
Redemption
Try to use Redemption on cooldown, when your allies are missing some health. It is best to use when they are grouped. Especially if you already have Moonstone Renewer, it is best to wait (or ping) until they group together, so you can have them all healed.
Remember that you can use Redemption for the damage. However, in general, it is not worth it. Keep it to heal your team!
Be careful when using Redemption while you are dead, and you are about to be respawned. The camera will go to your position, and you can cast it in the spawning pool by mistake. Watch out for bad timing!
Tips and Tricks
Champion
Your auto attacks do more damage when hitting an enemy from behind. You can use it for farming minions and for damage versus champions. Position properly!
Beware of any DoT effects on you! They make your shape visible when you are invisible, after using Deceive (Q). Pay attention or you are gonna have bad times.
Beware of enemy summoners and abilities that apply True Sight, because they reveal you when you are invisible! For example, getting hit by Mark (Snowball) makes you visible.
You can improve your Shaco game immediately just by changing direction before using Deceive (Q). Pretend that you are going one direction, just to Q into another. Works all directions!
You can use your boxes Jack In The Box (W) for bush control.
You can use your boxes Jack In The Box (W) to block enemy skillshots or to trigger enemy mushrooms/traps/saplings.
The placement of your boxes should depend on how the game is going on. Your team is losing? Better to start putting down your boxes behind you (because otherwise, you cannot protect them at all). Enemy team is full on engagement? You also want to put them behind your team. You are ahead and you can protect your boxes? Put them aggressively in front of you!
Riot
Using Deceive over terrain can help you make a clean escape.
Try getting items with on-hit effects. These will also benefit your Hallucination clone.
Backstab's damage can be increased with increased Critical Damage effects like Infinity Edge.
