So like the title says, I'm a beginner and I would like the help of people to get decks that are solid and that work in Modern. (I also accept standart because I have cards from aether revolt only)
You'll see my collection, I bought a Magic Booster Box (Aether Revolt) and there is a plenty of cards with a few lands (I can buy a few more lands) and I also bought Tezzeret Intro Deck to build a deck from it because I know I don't necessarily have a lot of cards in order to do a proper deck.
So here is my collection without Tezzeret Intro Deck, but if you want to know the cards in it to make me another deck based from it you can go on internet, there is the list.

Well, welcome to the Modern format
First off all things: you asked for a "solid" deck, and here comes the bad news: Modern is expensive and costly, expecially for a competitive deck.
Assuming that money aren't much of a problem (since you bought a booster box and those ain't growing on trees), you now have to consider some things:
1)With a box you won't do much.
You can barely make a standard format deck.
You need to start thinking about a winning style (control, combo, tempo, aggro), a winning condition (
overwhelm the opponent by sheer number, combo some pieces together to autowin the game, counter that s@@t!, etc...), and then sorting out the cards.
You'll probably need to buy the single cards out but, trust me, it's much more cheaper than buying boosters and boxes and hoping to find what you need.
Even more since WotC started to lower the average power curve of the cards in the newer expansions.
2)Which kind of player are you?
Do you take a more "thinking" approach to the game?
Or you just like to play whatever you have in hand mindlessly?
This conditions a lot the decks you can play because of personal affinity.
I can't stand playing aggro decks for example, it just feels... unnatural to me.
3)Once you defined your approach to the game, decide the colors, assuming that you know the strong and weak points of every color.
Again, this is personal preference: I can't stand red, barely tolerate green and black, but love white and blue.
Then we can start thinking about a deck.
