Haha...secrets secrets secrets.
Samus is our treasure. I am all for the benefit of Samus, but not for the sharing of info for the people who need advice on owning samus. I only give out the secrets to other samus players, i dont want a shiek to come in here and figure us all out.
It's an exclusive club, we are too cool to share with those lame *** characters.
But yeah, alexander, instead of throwing a shiek up, you can throw down for a guaranteed fsmash or ftilt (if they DI away from you). If they dont manage to DI correctly, you just landed yourself a KO with a forward smash. I have never been in a situation where an up throw on a shiek has worked. Again, unless they actualy fast fall into you afterwards...because as i understand it, they are fully capable of jumping before getting hit.
And yes, with falcos, foxes, and falcons, it is good to throw them up. With the dthrow at low percentage they fall so fast to the floor that they can tech the throw before you can land a hit. Of course at high percentage you can combo with idk, same things as other characters, but it is still harder to land if they DI away from you, and the slower moves wont get close to touching them. Falcon is the easiest out of those three to hit off the dthrows, but it is still limited. But if your opponent is at 140, they can still jump out of an upthrow, so then you should switch it up to a dthrow at 100+.
