Yep - the more I see Jacek in battles, the more I like him. But when you play Jacek, then throw in Sinash and Supply Runner both using SWIFTNESS - That's +4 speed. It's a great way to really stuff your opponent's up - if they can't hit you, or don't get a chance, can certainly change the game to your advantage really quickly.
