The upped version is too powerful. Starting from turn 3 it goes even, turn 4 on it gains esponentially. The unupped might be intresting.
But then you will either need an Entropy Mark or a bunch of Amethyst Pillars to utilize this card to its fullest extent. Generating Pillars for other elements other than Entropy is fine, as you will need to draw this AND a pillar of the element your deck is based off of, but if one is running a mono Entropy then this card is OP.
I suggest the revamp to be: "

[insert ability name]: Generate three random pillars not matching your mark."
I took out the pendulums because I think this card is meant to be a new way to run rainbows, not duos. This random pillar generation is nowhere near OP because you only have so many permanent slots to be filled up with pillars.
