>40 cards
Fine but why not the usual 60?
>17 lands
Good benchmark for 40 card decks
>+ other cards with 2 artifacts, 2 instants, 2 sorceries in each deck
Different decks need different things. Do not limit yourself like this.

>Any general advice hot to do this deckbuilding in order to make deck approximately balanced? I do not want to make something annoying as hell.
If it's all commons, it should stay pretty balanced naturally. Blue is annoying to most new players assuming you run counters, but that's just how it is. Budget control is shite in multiplayer anyway so it works out.

How about you do a rochester draft?
You dump a bunch of cards on a pile, and one by one you each pick a card?
if these people are new, you might also look into what the decklists of those free giveaway starterthings to get ideas of what to use.

Use a 60 card deck, you only have commons why add insult to injury.
Next you'd be well off using 15 lands, mana producing creatures somewhere around 25 mana producing creatures, 20 artifacts. Try that, im sure you'll be fine.

Did your mommy not love you enough?

Is your dick a size of babbys' pinky finger? Size of a small knob?

I am right on both counts.

I would build tribal. Goblins, Humans, Faeries, shit like that

Rochester draft or build a cube. Cube would take more time since you'd want it relatively balanced.

You have absolutely zero fucking idea what you are doing, do you?

Or are you tolling?

Honestly, balancing decks is quite hard. Doing that well will be a lot of work on your part, since there is no real formula for it. Though the most important thing would be keeping an even mana curve, so the decks have similar amounts of cards at each cost.
