This comp revolves around Viktor as the main damage carry and uses Silco to allow Viktor to cast his ability quickly. The comp uses a lot of late game units, so going Fast 8 is recommended for this comp.
Go for this comp if you have enough gold to Fast 8 and have good Viktor items. Finding Silco and Viktor at level 8 is also important.
Level up to 4 early if you want to start a win streak. Level up to 5 to try and continue the streak.
If you're weak in the early game, you can opt to save gold and lose streak instead.
At Round 3-2, level up to 6 regardless of your start. Put together the strongest team you can.
Level up to 7 at round 4-1. Roll down to stabilize your comp if you are weak. If you can hold off, try to save up for level 8 before rolling to leverage your economy.
Save up to hit level 8 at 5-1 or earlier if you have enough gold. Leveling up at Round 4-3 or Round 4-5 is great to increase your chances to hit higher cost units. You can then keep saving and roll down at 5-1 to find all your upgrades.
If you have stabilized at level 8, look to hit level 9 to upgrade all of your 5-cost units.
When you're at level 8, you likely will want to drop Ziggs and save him for level 9. Ziggs will provide Arcanist and Scrap, but is the weakest member on the team.
