Request for HS visual assets

Hey, I'm looking to create some custom graphics, effects similar to Shadow Form or Cursed Blade, that appear over top hero portraits in the game. Has anyone pulled these various graphics out of the game in a usable format? Does anyone have homemade versions that approximate the visual effects?

Here's an image showing the stuff I'm talking about. Cursed Blade debuffing the hero and weapon with a red glow. The frozen and immune and shadow form hero effects too. Also, anyone have the reborn graphic?

Googled for a bit because i was interested and came up with mostly nothing i found these:this was from a frozen throne reddit post about hero powers https://www.reddit.com/r/hearthstone/comments/6ltdnt/kft_bosses_hero_powers_images/

That's all i found, there was this other freeze effect stuff from a chinese site i didn't bother linking because it was blocked by a watermark, it's not hard to find on google images if you're really interested in it but trust me it's a dead end, i only looked up the freeze effect because i assumed it would be the easiest to track down, the cursed blade one looks really simple to duplicate if you own photoshop and the shadowform one went nowhere when i checked it out, I say good luck.

Yeah, I suspect the reason why these things haven't been ripped out of the game yet is because they aren't stored as some kind of simple 2D image file. At the very least, many of them are 2D things stretched onto 3D objects, but I bet a lot are entirely generated within unity.
