Vendillion Clique doesn't work, it makes you search your library for some reason, then you just draw a card.
Also I tried casting
Artillerize and
Immolating Souleater in my Scars block draft and the program didn't do anything no error report or anything, I could keep playing and all other cards seem to work fine, it's just as if these cards had no text. When I used
Kuldotha Forgemaster to search out
Immolating Souleater it entered the battlefield fine, but when I block my opponents
Auriok Edgewright, it didn't die, despite receiving 2 damage. And when my opponents
Priests of Norn blocked it I couldn't pump its power, it became a 0/0, yet still didn't die. I decided to try sacrificing it to
Kuldotha Forgemaster, managed to somehow select it for all three sacrifices and it still didn't die!!! IMMORTAL SOULEATER!
Tried exiling it with
Into the Core, still alive, but now there's also a 0/0
Immolating Souleater in my graveyard with a -1/-1 counter on it...
I posted before about Kamigawa block spirit triggers (when you cast a spirit or arcane spell) it happened again with
Embersmith, its ability goes on the stack, but the spell that triggered it disappears from the game.
