First of all, let me congratulate to you for making into the Top 8 :).
Now, about the article.
Really really interesting background of the card, I love how you mixed up some of black mechanichs and charateristics in the card. I like the idea behind the card. But it has something that doesn't convince me 100%... I don't know what, and I'm not saying the card is bad, just my guts don't love it as my brain
Anyway, I think that with the right mana cost the card can be "abused" (as you said, as a "heal" for drawing with Sign in Blood or against a nonlethal attack from an aggro deck). And I really hope it can go on.
Still, I think the card misses something to be tournament viable, I don't know what, but it's just that I have never seen Lich or similar enchantments played on a competitive level, but as you mentioned a combo with Hexmage could easly kill the opponent in one turn, so, I am probably too blind to see the potential of the card
Good Luck with the voting! And keep creating good and balanced cards like this one, I think you're good at it
And triggers every single revolt without spending mana
It is literally Caller but it puts Scions instead of bears and it does so upon cast and not etb
Could it be Vile Redeemer?
Well probably, but as it has been pointed out it can't be Malignant or Evil since it's #125 and it's after Scion. It's probably something like Vile Redeemer.
Updating anyway
Posted tonight, didn't see it anywhere here, if I'm wrong, delete it:
Name should be Vile Redeemer but I'm not sure it's the official name, text is as follow:
*something* Redeemer (?) 2G
Creature - Eldrazi (R)
Devoid
Flash
When you cast *something* Redeemer you may pay C. If you do, put a 1/1 colorless Eldrazi Scion creature token onto the battlefield for each nontoken creature died under your control this turn. They have "Sacrifice this creature: Add C to your mana pool".
3/3

Edited to respect collector's number. Name could be Vile Reedemer.
Unless they decided long ago to include titans, no. Remember: the sets are actually designed way before they're released, and Bloom Titan deck is only now rising to popularity, but the set is probably already done since months
Justo take a look at the ":" near the loyalty abilities and how they are at the same height for the actual and recent planeswalkers but they drop for Ugin. There is no reason for it, except for the card to be a fake
