How does infect work with mtg?

here's the stuff you need to know :)

-infect deals damage to creatures in the form of -1/-1 counters

-a -1/-1 counter on a creature is permanent

-a -1/-1 counter reduces a creature's stats

-when a creature ha 0 toughness it dies

-infect creatures deal damage to players in the form of poison counters

-when a player has 10 poison counters they lose the game. it doesn't matter how much life they have left

At the end of the battle phase the blocking creature would have 2 -1/-1 counters on it making it a 0/1.

Infect is permanent.

When a creature is lowered to 0 toughness or less outside of the battle phase, then it;s out right into the graveyard.

im still new to the game but if a monster has infect, instead of normal damage they do a -1/-1 debuff. i say its a debuff because thats the only way i can remember. infect damage dont disapear during the end phase. so if you have a monster with 2/3 and they block an infect monster with 1/1, then your monster is now a 1/2 unless you have a card that removes the infect counters. like the basic rule of magic, if your monster has 0 block then they die. if you dont block an infect monster, then you get a infect counter, and they dont disapear, unless you have a card that says so. once you get 10 infect counters, you lose
