Ledgetrapping
Here are our most common ledgetrapping methods:
Nairtrapping - Repeatedly using sh ff nair to catch a neutral, jump, or drop down into aggressive option getup. Even before nq starts putting opponents into tumble we can start killing with nq runoff fair. One of our best ledgetrapping tools.
Bairtrapping - Putting ourself at roll distance and spacing bair catches the previously mentioned getup options and can also catch roll by using the hilt of the lance. This becomes incredibly strong with bf/sbf platforms since we can land on them with a full hop bair, catching jump from ledge, and then drop down from the plat into landing bair to cover the other options.
Fairtrapping - Similar to bairtrapping but less committal for less reward. Not used too often but good for pressuring a neutral getup into immediate shield.
Lancetrapping - Using fsmash to ledgetrap. More details explained in the video by GiMR below.
