Winberrls are just trolls, and they are fairly easy to troll with once you've figured out what you need to do. Get two machineguns (rage machinegun/beam machinegun work pretty work, Beam Machinegun especially if you can get it, since you are Land units' worst nightmare), hide behind a rock on the backline, poke your head out every now and then and fire ALL weapons at whichever unfortunate soul you see in the battlefield (even easier if they are Jikuns ramboing into your side's defense trying to cause havoc), drag him to you and friends, release bind, cancel and riddle the bastard with bullets, rince and repeat. Most important thing is not to be on your own and not to be on the front line, you do NOT want to be eating bullets whilst trolling.
EDIT: ^ Oh? Well, honestly, their pull+bind combo work pretty well on all three types, but Art seem a lot more resistant to the stun than the other two, and besides, you won't find much Arts to pull on the front line. Air are just so much harder to actually aim at, unless it's an inexperienced Air that runs out of gas in the middle of the opponent's defense :V As for Jikuns, I've yet to see one that managed to melee out of the pull+bind, they are way too stunned to get out of the mess everytime I've trolled them.
