This would probably work better if it was changed to a permanent, or made a one time spell.
the effect is that for every relic you have in play/played when you win you get another 25% the score and electrum you would have won, and when you lose you decrease the score (and money?) lost by 10%.
so with one relic played you get 125% for a win, with two you get 150% and etc up to 250%.
for a loss with one relic you will lose 90% the original score, with two you will lose 80% and etc down to 40%.
this card would have no effect in battle, but it would be useful in stalls and deckout decks, potentially making them just as worthwhile for grinding as many of the rushes primarily used.
