Lets go looking at the passive, because the Spirits dont get haste, nor do they keep the abilities

Theres a little competition from cards like Glare of Heresy and Revoke Existence that often do similar jobs, but I think well find that being an Instant is a lot more valuable than killing the few nonenchantment artifacts that see play and that there are enough nonwhite enchantments that you cant rely on Glare of Heresy to answer enchantments (though Glare of Heresy will keep seeing play, just not in a competing role with Deicide)
This Basic card can deal 30 damage for each Pokemon on the bench with its Circle Circuit attack using just 2 energy
Also good in other decks, like Winota, Joiner of Forces and Neyali, Suns' Vanguard
