Hi
I think this Mu is 55:45 for Falco.
Falco can CG Ike and releases him = free 45% about and maybe a kill on certain stage ( definitely Lylat or DF, juste CG to dair then Footsool/Bair, and edgehopping him
).
Falco's Jabs is very effective on Ike: with the 3rd jab you can release Bdown or Ftilt, it works 80% of time cause Ike's landing lag.
But Ike punishes Falco easily: if Bside is predictable, it's free Jab to Grab or Usmash for Ike...
Ike's jab cancel is effective too: he can grab you and F/Bthrow to dash attack (it's a true combo).
The best advantage of Ike in this MU is his attacks' Knockback and their range. Falco can kill a good Ike about 110%-120%; but Ike can you earlier with his Fair, Bair, Filt, etc... about 90%.
But Falco balances this advantage with his laser game.
Later, I'll speak about stages and advantages
. See ya!
