Spider-Man Rare Quadruples in Price Thanks to Entirely Different Universes Beyond Set

Avatar: The Last Airbender is turning out to be a fairly impactful Magic set. As we reported last Monday, both airbending and earthbending are seen in top-tier Standard decks; Badgermole Cub has become a multi-format staple; and Fire Lord Azula, the poster child for firebending, is Avatar's most popular commander right now.   

And all this firebending has nearly tripled the price of a card from a completely different Universes Beyond set: Electro, Assaulting Battery.

Because, well, that's Magic nowadays, for better or worse: A game where a team-up between Spider-Man and Avatar villains is a thing!

Electro, Assaulting Battery is pretty much Birgi, God of Storytelling at home, stapled onto a big fireball when he dies.

“You can keep unspent red mana indefinitely while Electro is under your control,” explain WotC's  Jess Dunks and Eric Levine in Spider-Man's Release Notes… and indefinitely is the key word here. “If you add a red mana during one step or phase, you can spend it during a later step or phase, or even a later turn.”

You still lose other types of unspent mana, but Electro lets you keep accumulating mana indefinitely.

And that's not just a cool trick: Even way before Avatar, Electro, Assaulting Battery was already seeing quite a bit of cEDH play, often with Ral, Monsoon Mage in the command zone, sometimes with Etali, Primal Conqueror.

But then, firebending happened, and Electro, Assaulting Battery‘s price sky-rocketed, shooting from about $2.50 to almost $10 for near-mint copies in the US market:

“Firebending N” is a keyword that lets you add N red mana when the creature attacks, and you get to keep that mana during all the combat phase. That's to say, you don't lose the mana until you leave combat and go to your second main phase (you can use that mana even after combat damage has been dealt!).

Obviously, Electro, Assaulting Battery lets add “And you actually don't lose that mana ever, as long as I'm around, since firebending creates red mana.”

That had made Electro, Assaulting Battery a staple with Fire Lord Azula, Avatar's most popular commander…

… being also frequently seen when Fire Lord Zuko or Ozai, the Phoenix King are in the command zone.

And speaking of Phoenixes and firebending…

… Ozai, the Phoenix King has lived up to its moniker, rebounding by nearly 100% in the last couple of weeks:

Unlike Electro, Assaulting Battery, our Phoenix King sees nearly zero competitive play. But he's become quite popular both as a commander (which has also contributed to Electro, Assaulting Battery‘s spike as nearly two out of three Ozai decks play Electro), and in the 99 of Fire Lord Azula and Fire Lord Zuko .

Ozai, the Phoenix King‘s ability is similar to Electro's but it turns any unspent mana into red mana. So, after Ozai does his trick, Electro can keep it around forever (and Ozai himself suffices to hold that mana even across turns!)

With our usual caveat that this is not investment advice (always do your own research, folks!), Electro, Assaulting Battery‘s momentum is quite impressive, and it's fueled by two different factors: Its cEDH punch in decks that have no interest in firebending, plus a huge interest in casual firebending decks.

Ozai, the Phoenix King‘s case is a lot more unclear: At the moment of writing it's already a bit in the downswing, and it has not yet proven any viability in competitive or 60-card formats.

Then again, both of these cards are in pretty low supply right now, with current inventories enough to supply 4-5 days of demand.
