Board Game Arena

I found two possible minor issues or conflicts with these cards when playing seasons
1. Rattie nightshade, when you take energy from your opponents, and you go over the usual 7 energy limit it allows you to hold the energy. (you can hold up to more than 7 energy when this card is played)
2. Thieving faieries, people can still use activated abilities when they have no crystals, is this intended? Note: but for arcano leech people can't summon unless they have crystals.

1. It is known bug
2. The text on each card is slightly different.

Arcano : In order to summon a power card, your opponent must give you 1 crystal first.
It implies the opponent can't summon a power card if he doesn't have any crystal to give you first.
Fairies : Each time an opponent activates one of their power card, they must give you 1 crystal [...].
It implies that the opponent first activates his card, and then gives you a crystal, if he can.
