Quote from Legend »But the creature you presented to exemplify that precedent is thoroughly erroneous.
Do you mean Spinebeast or Piecemeal Hydra?
Quote from Legend »Etched Monstrosity was intended as a foil to Infect.
Not sure what you mean here, either. By a foil to infect, I assume you meant against creatures from the same set that have infect, like Razor Swine? In what way does Etched Monstrosity specifically work against it? Does the 10/10 block Infect creatures to accumulate -1/-1 counters, and then activate its ability to draw 3 cards, then rinse and repeat? If that's the big foil, cool, but I've never seen it happen or even heard of it happening. Are we talking Constructed infect decks, or limited? Because if it was meant to foil Constructed infect decks, it has failed miserably. If it was meant to foil Limited infect decks, why did they give that task to a mythic? I don't get it.
Anyhow, I'll consider it a 5/5 (not 5/5+) for , for the purpose of my master list. If you're playing it in a colourless deck, you can't use the activated ability, so it's vanilla. It's only 5/5+ in a deck.
