Who can explain to me the magical aggregation poisoning index in detail?

When the player gets ten poison counters, he loses the game.

Infection means that the creature is hurt by-1-1counter, and the player is hurt by getting a poisoning counter.

Legend belongs to "super category", not biological category.

Ghosts, goblins and goblins are actually a biological category, but when Magic Gathering first entered China, his translation was wrong.

The biological boundary is a halo, but it is called differently.

The interference is instantaneous.
