Empty Jar is the most frustrating thing of all time.

I personally play a Wetlands deck that uses nothing but level 2 aqua monsters, but no frogs. It focuses on locking down your opponent so they can't attack, switch from defense position, or summon anything strong, while I super-buff my weak little shits and attack directly over their entire board. It's not exactly a troll deck, but I've gotten lots of salty "I can't fucking believe you beat me with that shitty gimmick deck" comments.
