Rogue Phoenix Fire
I was clueless. I don't have that card and have only heard it in passing, so I was like "There's my 6th portal. Why is it being weird? Why is it still being weird?" *checks portal count* "What the hell just happened?"
XD its a fun card, if used properally it can really turn a game, if used incorrectly there are a few ways you can lose the game with it
(if you dont know how it works it causes 50 damage to all units on that portal (only non-home portals) and unscores it) Which means if you are attacking it you can steal it from the other person, or if it was a shared one like in that case, you can retake it and removed the other persons claim to it.
Of course if you dont attack that portal on that turn, it damages the units there, unscores and then rescores it to that person.
