I didn't see this posted anywhere, or covered in any past discussions, so I feel like bringing it up:
How do people like dthrow near the ledge? It covers tech in, tech in place, and no tech, and you can turn around and shoot a laser before their tech roll finishes if they tech in place, and continue applying pressure.
3 out of 4 tech options are punished by dsmash, and 2 out of 4 by dilt, both being good killing moves.
Fthrow is guaranteed to put them in a bad position, but dthrow has better payout if you react/anticipate correctly.
