As much as wish Nagase had Kyoshiro's symbol spread, she doesn't, but her ability to give -5 and 6 damage to every attack you play with LoTM (if the deck is built right) and have built in Hand Destruction/Momentum Gen?
Also, ::Alex:: is beastly. I think if someone makes a solid deck off of him it will be a terror to behold, if simply because boomerrang raid's damage pump is static
Hugo's handsize is deceptive with his draw power, same with Sogetsu. Mina though... Mina's F answers the question that you have to ask in any deck that doesn't one shot is "How do I recur my win condition?"
