The name of this collection is clearly linked to Operation Phoenix—they are part of the same update, released in February 2014. As for the CS2 skins, the Phoenix Collection includes absolutely epic and amazingly beautiful weapon finishes.
AWP | Asiimov is here! It brings the iconic skin family to arguably the most popular Counter-Strike gun. The price of such an explosive combo is not too high, even if the item is still rather expensive. AK-47 | Redline follows the same recipe but with a darker and more ascetic art style. These top-rarity skins from the Phoenix Collection are worthy investments indeed.
The rest of the skins here are significantly cheaper. As for the artistic value, don’t sleep on brilliant SG 553 | Pulse and hilarious AUG | Chameleon. Both guns are effective in the game, and you will have a chance to show off with awesome items.
