Early opening

Item Holders + Augment
- Rek'Sai is the item carrier for Malphite.
- Malphite is the best solo mega tank, therefore you want to prioritize Gargoyle Stoneplate.
- The augment "Solo Plate" is the best at 2-1.
- Kha'Zix is not a Blackthorn but he is really the secret sauce for this line. When you see him dropped from orb, you should definitely consider Blackthorn.
- Kha'Zix can evolve Executioner Trait and Ravager Trait on himself to fill up this comp, and he is a 3 cost champion which you can reroll together with Azir at Lv7.
- When you are making Warwick and Veigar items, you really don't need to consider what's best on them (Because you are not playing Warwick reroll), they are just item holders for Azir and Kha'zix later on, so make sure the items you make are actually good on Azir and Kha'Zix.
- Use "Portable Forge" augment to get Ornn Artifact, the best artifacts are mentioned in the end of this guide.
When to roll, How to roll
Mainly roll at Level 7, since it gives best chance for 3 costs and decent chance for 4 costs (Mainly for Malphite).
Don't be obsessed with the interest of 50 gold. As a reroll comp player, you must seize the tempo of mid game! You must make the fast 8/9 players feel the pressure from you. You need to be pretty strong and oppressive even if you are not the strongest.
Therefore, even if you have to roll down to 30 or 20 or even 10 gold to make you strong enough at mid game, you should do it. But always make sure you don't roll too much at one round, and always leave a little bit of econ, so that you don't stuck on 2 stars.
Key Factor
- You will need an Blackthorn Emblem On Kha'Zix, that's the key for this comp.
- Blackthorn Emblem is made from Spatula + Belt.
- The Spatula could be from many resources, so don't worry, it's not a small chance to get a spatula in general.
- The resources include "U.R.F" "Urf's Gambit" augment, carousel, and orb drops from PVE rounds and many more.
- But in general "U.R.F" augment is the most straight forward way.
- Once you get your main tank Malphite (4 cost), and Blackthorn Emblem on Kha'Zix, you can assemble 6 Blackthorn.
End Game Comp + Board
It's really simple.
- Play 6 Blackthorn
- Solo front Malphite,
- Everyone else stay back so Malphite can maximize the stoneplate value,
- Kha'zix on the middle hex so he gets buffed (don't do that before you have 6 Blackthorn),
- Azir at the far end.
- Add in Zyra and Kennen at Lv7 and Lv8.
