jup, yusei's screwed.

Since all the duels so far have been ground duels, we can assume that Yusei's duel will be ground too. If so, he's screwed.
- You can't summon a savior when you're not on a motorcycle, since you get to fly in the monster with your motorcycle (check it if you don't believe me)
- To Accel Synchro, you have to go really fast, otherwise the card won't appear (notice when, Yusei's about to summon SSD, the card is blank until he is at his fastest point?

So yeah, bye Yusei.










Nah, just kidding, he still has Junk Berserker.

hahaha could be, but we don't know is it impossible to accel synchro on ground duel
we just never see yusei summon SSD on ground duel

Bruno always said that you have to achieve a clear mind to get your momentum at full power, so you could go at full speed. So unless Yusei starts running in circles, he can't :p

lol running and duelling together?

yusei : synchro summon *hosh hosh haaah* be born *huff huff* Shooting Star draaaaagon *huff huff*

he will be dead before he summon SSD

I think it will be a riding duel.
But a ground duel would be funny and is not impossible to form Accel Synchro because the momentum in the Arc Cradle is very big, bigger as the momentum in a D-Wheel.

No, you cannot.
From wikia:
In the anime, it has been implied that in order to perform this type of Synchro Summoning, one must achieve Clear Mind at the time. You also need to have extreme speed.

This was an idea.
But the last episodes will be epic.
