Among the Avatar-themed cutest Magic cards turns out to be a formidable little force.

MTG’s collaboration with Avatar won’t get a wider release in the coming days, yet after prerelease weekends recently, one cheap green card saw a sharp rise in price.

From the initial reveals, the earthbending cub garnered a lot of attention. A 2/2 priced at one green and one colorless mana, it features the Earthbend 1 ability (arguably the best among the elemental mechanics available). The major perk with this card comes from its second ability: Each time mana is generated by tapping a creature, it provides bonus green mana.

When first listed, the card sold below $30. Following the early events, however, the going rate has shot up to $49.66 including listings as high as $60. Why are we seeing Vivi prices on this adorable card? Mostly due to the rapid resource generation it enables.

When it arrives the board, this creature transforms one land so it becomes a creature that has earthbending. And with that second ability, while it remains on the board, those lands produces twice the mana — along with mana-producing creatures you have that generate mana.

An ideal partner for maximum effect includes the classic Llanowar Elves, a cheap 1/1 that produces G mana. But numerous other mana generation creatures out there. This particular druid is a more expensive alternative with stats 1/3 for two mana as an alternative.

By playing lands, dorks that generate resources, plus the cub, it's simple to summon a massive and very expensive monster on the battlefield within a few turns. And things just keep spiraling rapidly with continued aggression from that point.

When adding a secondary color with this approach, options such as Fuel Tank Feaster, Ilysian Caryatid, and Paradise Druid are all great options that can make any color of mana. Additionally, this powerful dryad enables playing an additional land each turn as well as makes all of your lands into every basic land type. It's also worth trying something like this six-mana enchantment, which for six mana provides every card you own the power to tap and generate one mana of any color — including each creature you have on the board.

The cub might seem overpowered when it comes to ramping up your mana generation, but what closes out the game in such a strategy? One obvious and popular answer has been this legendary creature. Its stats are set by how many lands you have, and it makes your non-token creatures to be Forests along with their other types. In other words, all your creatures you control can tap for two G if used for mana.

Another creature is a costly, large threat that benefits from a high land count (similar to Ashaya, its power and toughness are based on your land total).

This Planeswalker is an excellent fit in this deck. Her passive ability makes Forest lands generate an additional green mana. (With a Badgermole Cub, this results in all earthbend forests produce triple green.) Her main ability functions like an early earthbend, putting +1/+1 counters on a land, a useful effect but it isn't redundant with earthbend. The minus ability, however, grants all of your lands immune to destruction enabling you to draw out your remaining Forests from your library. Once you trigger this power, this typically means game over.

Badgermole Cub is a must-have for any kind of green Avatar deck that use the earthbend mechanic. If you dip into red-green, there’s Bumi. It possesses earthbend 4, and when it hits a player in combat, all land creatures are ready again for another attack. Even though Bumi has emerged as a fan favorite Commander, this small creature will surely stay one of, if not the most popular pick in the collaboration.
