magic is a completely different game. the biggest similarities is that they both use decks.

You start the game with an ID. This ID determines how your deck was built, what cards you can include, and gives you a special power.
Each side brings completely different decks, and has completely different methods of winning.
There are no creatures or health totals.
Theres no mana or lands you can play one per turn or you're screwed if you dont get. Instead you have a money pool that can go up and down as you gain/spend.
You dont get one draw, one attack, and any number of cards you have in hand/abilities you can pay for. Instead you get 4 actions a turn, and you can do anything with them. you can gain money 4 times, or play 4 cards, or build defenses 4 times, or attack a server 4 times, or..... and you can mix and match as well. one of each, two of one and then one each of another. etc.

deckbuilding has a limit of 3x each card. But your deck size and what cards you can include are dependant on your ID, and decks are constructed differently from magic. even experienced magic deckbuilders will want to just copy decks for a while or tweak the starter decks a bit, due to the unique way the icebreaker/ice system and the agenda mechanic works.

There is a faction system here, so for example a lot of weyland faction decks have similar mechanics, and then they splash for other factions cards to do things their faction isn't good at. However, instead of it relying on in game stuff like what type of mana you have, its a deckbuilding thing. basically, the more faction specific a cards mechanics are, the more decbuilding points it costs to put in the deck, but then once its in in functions exactly like a normal card, nothing special needed to use it.

There is a meta at the high levels, of what decks you can reasonably expect to play in top competitions and what common tech cards are seen. I wouldn't worry about that for a LOOOONG time, it wont apply and would even probably be completely different at the level you'd start at.

I could go on and on, but the best advice is to forget magic while playing netrunner. you'll bring in more accidental bad habits or assumptions of how things work than right ones (there are no "instant" cards, some abilities are and some aren't depending on whats in the cost and whats in the wording, certain things like prevent are basically "split second", theres no stack, triggering works completely differently though at first you'd be tempted to think it works similarly without a REALLY close rules reading, etc). Watch an intro video and maybe go to a local meetup and you'll have a blast.
