Sorry that it took this long for me to get back to you.

Game 1

First impressions -

Starting off with 0 regen on NS is fine (provided you follow up with tangos like you did), but I would spend my gold on better stats, you went QB stick circlet branch x2 where I would've gone gauntlet tangos 3x branch, NS has very very high base stats and you can really lean into that.
In an deal world on NS you want to cs and deny every single creep for the first 5 waves, kind of just because you can and they can't do anything about it. You hit harder, faster and tank hits better then most if not all heroes in the game lvl 1.

Laning -

You start your lane by aggroing ranged, which shows me that you know how that works, but maybe not necessarily when to do it, PA as a hero lvl 1 is extremely weak, necro lvl 1 is even weaker (probably top 5 weakest lvl 1 heroes imo). I would aggro to ranged and then beat the living hell out of both of them immediately. Remember that NS essentially starts the game lvl 2 with the night reign facet.

I really hate that you went 0 stats into ring of heath, NS is a hero that revolves around stats and movespeed, and if you go bracer corro or double bracer i'm certain you just globber necro to death until like lvl 5, especially since you have a venge 4 which amps your phys damage.

There are some other major mistakes during your lane (including lotuses / xp rune) but to keep this short and easy to learn from:

- Hit the enemy more, especially on nightstalker
- Favour stats over a naked ring of health
- Abuse your timings (i.e. being lvl2 when they are lvl 1)

Early game -

I really hate this vanguard (and subsequently halberd) rush, of 5 players on their team only 1 of them does physical damage and he's the guy that's never doing to show up to fights, so essentially your vanguard is null and void. Undying does magic, pudge is magic, necro is magic and PB is entirely magic. I would not consider even buying halberd on NS unless they had 2-3 right clickers off the bat. Instead I would've focused on stats, probably going something like midas sny or blademail sny since it's a pretty decent blademail game.

Pretty weird buyback play at min 15, I don't hate it but you shouldn't have died initially

You seem to try to force towers (and thus fights) when your ult is CD and it's day time, NIGHTstalker becomes AFKstalker when both of these things are true, it's probably the only hero in the game that is hyper aggressive then hyper passive for 5 mins at a time. i.e. do NOT fight at day time with no ult EVER. Does not matter if your team is crying, spam pinging, sieging hg, diving fountain, i'm afk till night or until my ult is off cd goodluck.

You take the top tower, and then run mid, which I think is the correct play. Your team does some weird dive t2 and feed play which I absolutely think you should ignore, slark comes mid and takes tower and a free pudge kill, this is all very good. You seem to do a good job of setting tempo at day time

Mid game -

Min 25 you go for a risky dive without ult, as it's turning day, generally I would avoid team fighting without ult, the free pathing really is what makes this hero absurdly strong, especially as you can just fly over HG and they can't chase you. This whole fight should just have been avoided imo.

Taking the status res lvl 15 is also what most NS players do, it stacks with the SNY and makes you more or less unstunable

After your echo + blink I would consider a BKB, you have little to no magic resist against 4 magic heroes (and a pudge with an aghs) Alternatively if you're feeling freaky you can buy a mage slayer, it's not good on this hero but its an insanely good mage game for slark, who refused to buy it for some reason.

NS shard is also like a buy every game before min 20 kind of item IMO. the sustain means you literally never have to base and also you can use your full hp bar like 2x in a fight.

Late game -

Min 30 you again take this daytime no ult fight, and die, who would've guessed, team fights without you (and also dies) unlucky.

You wait for your team to respawn, which is perfect, I would be telling my team to A) smoke then rosh or B) if you're strong enough rs then smoke.

Instead you take a good fight and wipe them (also fine), take 1 rax, and then back ???? Why not take another rax they are all dead for another 15-30 seconds each, you also have all of your buttons

Taking rosh was fine in the end, you guys take mid rax and then for some reason ignore the bot rax on 200 hp, you alone could've taken this secured megas, and more or less guaranteed the win

Sniper does some actually schizo play min 40 and you decide to fight with your strongest core dead, I would immediately call back after this guy feeds, this fight makes the game really hard again. From

Min 47 you guys again dive hg with rs alive, I would never go HG in a game unless we have A) 30k gold lead B) rosh and a siege hero C) 3 of them are dead D) all of the above, I also think you should prioritise taking this last rax over fighting people, thankfully you take megas but you also all die

Late game NS becomes less of a go-in-and-kill hero and more of a give vision and bait spells heroes, the free pathing means you can take a spell or two and fly away without ever hard commiting, since it's alot harder to do that late game when people have items.

Min 52 you try the HG again, but by this point any lead you guys had is long gone, the enemy is actually now up on NW. At this point dota matters alot less about items and matchups and it really just becomes who jumps who, you should be looking for aggressive wards on the side jungles here and waiting for someone to come off the HG and feed, alternatively you ult to give sniper vision and just idle in trees nearby, you don't have to commit all in.

No idea what this manta is for, I would honestly just buy another sange, for the status res on yasha, alternatively it's a very good nullifier game, you can also buy a linkens so that you can go in since they have 3 massive ults (2 of which pierce bkb)

Min 57, another schizo HG push from sniper, you guys really can't do this, from your post i'm sure you were telling them not to, just wait for RS and wait for a pickoff on the map.
