Can a card with a symbol-based ability trigger off a second copy of itself, and can its own symbol count toward its trigger?

Question

Accepted Answer

Yes for a second copy: the symbol on the first copy can enable the second copy's ability. A card's own symbol never counts toward its own trigger, since its ability needs matching cards played before it.
