This deck si RoL variant of old and very functional Rainbow rush and as a core was taken deck "mana cheat rainbow rush RoI" by badmadafaka (https://www.mythgardhub.com/deck?id=2380). It's faster now and there is more creatures to be used. I've also thrown away many of the expensive mythics, as there is no time to use them - when you are enough deep in the game to to cast them, you've already either won or lost. I've also put away those new minions, who operates with enchantments like Svinne or Seer, because again, they are too slow and in the early stages of the game you can't cast them together with the enchants. Therefore, they are useless...
Keep your minions in run, use Highway alot and it's gonna be fine :)
