Primary Idea: Duo Cards that Swap orientation when upgraded.
Secondary Idea: X=number of pillars/pendulums matching an element.
Tertiary idea: New Rare series
Typically suggestions only include 1 new idea (see Primary and Secondary ideas). With multiple ideas the worse idea tends to weigh down the better idea and vice versa.
Thematics: Name
Behemoth|Overlord really is only a suitable name for creatures (see

).
Also Behemoth|Overlord is generic enough that it works for any element provided the adjective is fitting.
However since these are Duo cards the thematic adjective needs to be evocative of both elements (Planetary fits Gravity very well and is okay for Earth, Verdant fits Life but is not associated with Water and Chaos is associated with a thematic subset of Entropy but is not associated with Aether)
But the cards also switch orientation when upgraded so the adjective for each card needs to have a stronger connection to the dominant element. (Planetary seems a little lacking in this regard but might work)
Mechanics: Upgrade
Upgraded cards are supposed to be better than unupped.

=

(upgrade insufficient)

>

(upgrade reversed)

<

(upgrade in the correct orientation. Magnitude might be too small, too large or correct)
Rarity
Why would these be good candidates for rarity?
[This is a hard question because most intuitive reasons are invalid]
Format
Cost needs the quanta symbol included
All cards could be edited into the opening post
(still), (again), (finally!) are not needed
You should put the name of the series in the Series box.
Card art needs to be full sized. Fix by clicking "more options" -> "no thumbnail"
Card art needs to be inside the table
Attack|HP for spells and permanents is left blank. N/A is incorrect (although it probably should be a creature due to the name)
