If you were to get rid of any card, a plate armor would be the card to go statistically. However I find it more so preference between enchant artifact and pulveriser. Pulvy is merely only really good early game, so rather than needing a starting hand of X(at least 2) pillars, pulvy, and artifact, I'd get rid of an artifact and hope my opponent didn't get early PC. That way the decks potential is more so increased, rather than the little higher consistency of taking out of plate armor.
