Myriad Payoff

Cards that reward or scale with myriad: triggered abilities that fire when a creature with myriad attacks, enters, or deals damage, anthems and lords for creatures with myriad, counts of creatures with myriad, and targeted support keyed on the keyword. The keyword payoff classifier emits one such tag per Scryfall keyword, and withholds it when the same card punishes or removes creatures with myriad (Plummet is a flying punisher, not a flying payoff). Distinct from the has_myriad tag, which marks cards that HAVE myriad rather than cards that care about it.
