most likely they hate being eternity locked, stuck using it to avoid deck-out once low. theoretically (and not realistically), you fly the pulvy or eternity, then use both. unfortunately, actual experience is that you are stuck with a garbage flying weapon card as you play more important stuff to survive, and need massive amounts of quantum to successfully execute the combo, which often isnt even "autowin"
oh, and you need quint too unless you rock gravity nymphs (did i mention the massive quantum issues to pull off this flying rainbow with infinite resources?)
