Invokers + Taric are a very strong comp. Galio received some buffs recently too which gives this comp a more stable early game. There is a 4 invover variant to this comp too which I have added at the end of this guide.
Final Board (6 Invoker)




























Legends & Augments
Legends
- Veigar - With the changes to how strongest units are decided in patch 13.14 I think being able to guarantee Jewelled Lotus will be very strong.
- Ornn - Ornn is still a very strong legend and you have a lot of units that can use Ornn items
- Vladimir - gives you a lot of combat power
Augments
The augment choices are fairly flexible, you just need combat augments to maintain your power.
- Jewelled Lotus
- Loving Invocation - Your team gains 4% Ability Power until the end of combat each time your Invoker units cast their Abilities. Gain 2 Invokers. Very strong in this comp
- Winds of War - It is possible to play the galio hero augment with this comp, you will just need to 3* him and put your items on him instead of Taric
- Magic Wand
- Idealism
- Healing Orbs
- Combat Caster
Early Game
You just need to play your strongest board in the early game, preferably with an AP item holder.
An example would be 3 Void with Malzahar carrying your AP items and Swain in the frontline to give you 2 sorc.
If you get an early Karma you can play 4 Invoker with whatever frontile units you can 2-star.
Mid Game









At level 6 you want to roll down a bit to stabalise by 2 starring your units.
If you hit an early shen at level 6 you can swap Cassiopea and Shen in for Taric and Kassadin, you can then put Taric back in at level 7.
At level 7 you slow roll for Karma 3 and Taric 3. You can also keep any Soraka's you find as long as it doesn't mess with your Econ.
Level 7 Board










Final Board (4 Invoker Variation)
































This version requires you have a blue buff on Karma to maintain it's stregnth. You just replace Galio and Ryze with Sion and Sejuani to beef up the frontline to allow your invokers to scale. With the buffs to Sejuani it's also a very good choice.
