Hello everyone, and please excuse my bad english.
I'd like to report a bug :
Cards we are talking about :
Necrotic Ooze : On the battlefield
Vish Kal, Blood Arbiter : in the graveyard
and any random creature with power > 0 : On the battlefield.
Necrotic Ooze : "As long as
Necrotic Ooze is on the battlefield, it has all activated abilities of all creature cards in all graveyards."
Vish Kal : "
Sacrifice a creature: Put
X +1/+1 counters on
Vish Kal, Blood Arbiter, where
X is the sacrified creature's power."
And then, we can use the activated ability, but it puts "0 counter" (It was a memnite in my tests)(according to the stack).
I tried with
Experiment Kraj, it doesn't work either.
Have a good day, and thank you for this amazing work you've done with forge

Edit : I just upgraded Forge, and 1.3.15 has the same problem. I Repost in the adapted topic.
