Before reflection I add 2 mana with her. After reflection, I still adds 2 (the other 1 is from tapping the forest).

@Rowsol Can you try with a gaea’s anthem in the battlefield? I want to know what will be the behavior. Trying to get better info of the bug. Thanks

I tapped the forest for 2 green, used her to add 1 of each black and red. No mana added by reflection.

Again, forest adds 2 green, use one for activation and add 8 due to 8/8. Reflection does nothing.

It simply doesn't do anything no matter how much mana you are adding. I'll note that my previous comment was suspicious because I noted it added a mana when it didn't, the extra simply came from tapping the forest with reflection in play.

I added all 9 affected cards in the Affected Cards list together with Mana Reflection. Fell free to remove those 9 cards if it's not necessary to have them in the list.

The other cards should not have been in the Affected Cards line.

The warning was popping up every time somebody played a Terrarion.
