WITCHES' REVEL: Card Index.

A Strike Spell.

7 ▲ Power

To Play:
Spend 9 Passion, except you pay 1 Passion less for each of the +1s on your spells.
On Play:
On Play: You may remove all +1s on your spells, then add them back to any number of your spells, redistributed as you like.
(If you add any to this spell, count them for overpower.)

Notes:

To check if you can play this card, start at 9 Passion, and reduce by 1 Passion for each of the +1s on each of your spells on the field. If you have that much Passion, then you can play this card by spending that new total. If you don't, you can't.
If you reached 0 or less Passion in the count above, you can play this without spending any.
+1s are tracked with counters on whatever they're added to. While added, they add +1 ▲ Power if on strike spells, and +1 ● Resistance if on shield spells.
When a spell leaves the field, any +1s on it are lost.
Adding +1s to a spell after its 'On Play:' moment has passed does not cause an overpower.
On play, remove all the +1s off your spells, and count how many you removed. Then, add exactly that many +1s back, redistributing them onto any combination of spells. You can put them back how they were, change how many each spell had, or add some to spells that didn't have any.
Before checking whether the ▲ Power of a strike spell causes an overpower, complete all the consequences of playing the strike spell card. This includes any 'On Play:' effects, the effects of this card, and anything else that tells you to do something as that card is played.
If these add any +1s, they count when you check for overpower.
