Using some upgraded cards make war MUCH more interesting. I'd wish there were more oppurtunities (also for regular war members) to use them. It just opens up a whole new spectrum of tactics like arsenic hitting through shields, pend/pillar splits, adrenamercs and flying weapon decks just to name a few.
I spoke a bit with QT about implementing more upgraded cards in future wars, I really like his thoughts about this subject.
To get back on topic: Grats with this Stroke of Luck team Gravity and Air, but this is going to be our round, trust me
