Send your superstars on trophy dates until their popularity reaches 100. Once it does, it usually stays there and will only come down a point or two. When all your superstars are at 100, you can just maintain the ones at 99, 98, etc. This will give you easy four star match ratings. Have as many rivalries as you can, and you will get five star match ratings a few weeks in.
Table: Move the Right Analog-stick to put your opponent on the table, do a lift up ultimate control move (chokeslam, suplex, etc.), go over to the table, and do a slam move.
Wired 2x4: Use the 2x4 to get a full momentum meter. Once you have a full momentum meter, get another wired 2x4, and press Finisher. Your character should light it on fire.
