Nodes of Power: Black Node Bug

I won with less 20 life some matchs, but the final pontuation was more 20 life. I think the node compute lifelink gain or another thing. I lost many points and rank because this.

That sounds like the annoying bug that has existed since time immemorial. The life you gained using lifegain is added to your pw’s health after the battle, thus rendering all your efforts to end the match at a certain amount of HP null and void.

Not total life gained during the match is it? I met the objective every match but used lifegain to time it.
Isn’t it just the life you gain when you are at full health?

The stupid objectives need changing to more than…who tries to win with less hp…?? especially when you get a hp boost at the after match summary

Yeah what everyone is saying if you gain life when full it adds it on at the end of the battle stupid I know just be careful not to gain life when full hp

I suspect that it is actually the planeswalker regen that does it, which honestly makes it even worse.

Normal PW regen ruins this too.
Just change it to MORE THAN (xx) HP

From my observations, the amount of life gained above your PW max will be added to their life total after the end of the match.
If you only use lifelink or life gaining effects when you have already taken damage, and never to more than max, if you end at 20 or less you should be okay for the objective. Otherwise if you gain more than max, or gain while at max, you will need to keep track of how much, and make sure you end with at least that same amount below the objective’s goal.
