Jadzi oracle of Arcavios not interacting with some ( most) drain mana effects

My planes walker:
Kiora

My deck:
Jadzi
Lullmage mentor
Mizzium meddler
test of talents
Summoner’s bane
Saw it coming
Jace’s sanctum
Genesis ultimatum
Body of research
Inspired Ultimatum.

The last 3 cards are just to play something big.

Jadzi does interact with Jace’s Sanctum, drain 2 and gain 7

but… she doesnt interact with Kiora’s first ability, lullmage mentor, mizzium meddler test of talents Summoner’s bane Saw it coming

Is that by design?

Edit:

Negate works
Ashiok nightmare weaver doesn’t work

I’ve been playing Jadzi with Mizzium Meddler since I got Jadzi and it has always worked. Haven’t really tested anything else from your list

Strange…
I’ll try mizzium again-----Yes mizzium meddler works-----

I have a feeling that it only works with origins cards

I want to add Archon of Absolution in the list also, but not because it doesn’t trigger Jadzi, but because I couldn’t get its effect to proc in the first place. I thought Jadzi and Archon would make a great pair, but with or without mana in Greg’s hand, nothing is happening. I know I got the Archon to work once a long time ago (Colors of Mana event) but it stopped working immediately after that first game and I never got it to work ever since.

Drain effects are mostly useless in this game (most of my unused/unmastered spells drain mana from Greg) but Jadzi made them fun and viable.

Maybe we can move this to the bugs section and the devs investigate and fix? @Oktagon_Support.

Thanks and kudos for adding a great card!

By using verdant mastery I was able to better test all this: first giving mana then taking it away…

I was wrong it seems, most if not all spells work, it’s the PW and vanguard abilities that don’t work

Loving jadzi! She makes drain interesting!
