Its very hard to differentiate between Prestige 0, Prestige 1, and Prestige 2. The difference in the banner is so minuscule that it is very easy to wrongly assume that a Prestige 2 player for a Prestige 1 and even Prestige 0. Only from Prestige 3, the UI difference comes out somewhat significant. I was at Prestige 3, but was thinking I was at Prestige 4 and waited to Prestige up to get Guaranteed Premium in first four cards in Kegs. Only after I Prestige(d) Up, I realized I was still at P3 only.
That player may be at Prestige 2 and yes, (s)he could have bought the starter pack and/or milled an entire faction (or several factions) cards to craft the faction/neutral cards (s)he wanted. I did the same thing when I started. I took advice from the forum - to mill an entire faction and craft a faction of choice - and milled SK (I chose SK for no reason when I knew nothing about the game and the factions) and crafted MO (as I started with MO). So, it is possible that the player did some extra steps to get the cards (s)he wanted.
In fact, you can also try that. Choose a faction which you care very less and wouldn't want to play and mill the entire faction cards you have accumulated till now. With the scraps you get, you can craft the cards you want (prefer neutrals first and then faction specific cards, so that when you want to play the other three factions, the neutrals can help).
