And I've explained, why that's not true. According to the magic pie article, black gets to remove all counters from any permanent (not players). Could that have changed in the meantime? Maybe.

Until you give substantial refutations that Black isn't the color of removing counters from permanents, according to official magic and cards they printed. Yes, you can make case that the article should have added white as well, but not that they are outright wrong.

They absolutely would. For a price. Black has even "combat damage" prevention on creatures, for a price. Oathsworn Knight.

Yeah and? In 95% of cases that distinction is meaningless. In 95% of cases, you heal for 1 and opponent deals 1 damage and you die. Or an opponent plays a "prevent life gain" card.

It's not parasitic, it synergistic with damage. If you are against a life gain deck, yeah you need to deal 20 corruption OR AND HEAR ME OUT - "prevent life gain". Because it's synergistic with damage.

This is reductionist thinking with which I heavily disagree. I mean, by your logic, before Kaladesh you'd say we shouldn't have colored artifacts, because there were like six of them.
