Lucky you. Lars/Leo happens to be one of best teams in the game. I forget the open ground combo if Leo starts but anyway.
Starting from Lars. These should work.
f+1+2~5 f,f+4,3~5 d/b+2~f SE d/f+1~5 TA! [Leo: f+3~d BOK1,2] f,f+2~f SE1_3(~5)
f,b+2,1~5 [Leo: f+3~d BOK4 KNK1~d BOK1,2] f,f+2~f SE1_3
Lars: W! f,b+2,1~5 [Leo: f+4~d/f~d/b ws141] f+4,1,2,1
Leo: W! b+2,1+2~5 [Lars: 1+2~b f+4,1,2,1] ws141 (Either the combo meter is broken or I suck. Because the dummy doesn't tech out if I set it to but the game doesn't count it as a combo either)
As for Leo's pokes. She's practically the same character she was in BR + some "meh" strings. So the stuff in the BR thread still apply
Your basic jabstring. h,h. -1 on block. +7 on hit. Gimmicky followup with 1,2,1,1_1,2,1,4 for those who are not patient. Crazy damage.
Basic i13 mid. doesnt track. -1 on block. +7 on hit.
Looks like a generic i12 d/f+4. But it's actually i13. Shocking.
pretty much the same as Drag d+2. Neutral on hit and ch. -13 on block
i16 low poke. -1 on hit. -12 on block
Generic d4. -2 on hit. -13 on block. instant high crush and tracks
Good range. -1 on block and a juggle on CH. Doesn't track anywhere. d+1~D will make Leo recover in FC
Good low. +5 on hit, a juggle on ch and only -11 on block. Crushes all highs.
Instant generic ws4
Good range, crushes well and tracks both ways.
I recommend watching Only practice matches from YT. He plays alot of good Lars/Leo.
