White-Peach
Smash Ace
On a grounded opponent (the only kind that can shield!) I use FAir mostly to pressure that shield :3 Getting a hit is just a bonus. BAir I like to land as close as possible (preferably behind them) and DSmash. When you're close you get more hits to increase shieldpoke possibility. And if you should happen to get the hit off of BAir, you link it to other hits. But a nice shieldpoke from the last hit of DSmash links into nice things too :3 I use BAir defensively, but I tend to think of it as my doorway to other things, whether they shield or not :D
