forceballs are the death of you, never let reptile pump these out non-stop, the slow ones are frametraps just outside dash distance and he gets a free blockstring when he dashes in after you've blocked.
Acid spit is 7%, ice ball is jip b121 to 2/throw 50/50.
Your goal in this matchup is to put that bitch in the corner and fuck its brains out, you have to be careful of his EX slide which as armour and will go through your 21!2 and of his EX dash which will switch sides and put you at -5.
EX dash is +5 but can be 22'd on his way back, risky option but even on block you can squeeze out a D3 clone which will keep reptile out if he attempts a 321 which is SPECIAL HIGH.
don't worry about ex slide unless you're nearing the corner.
when it comes to inyourface pressure, remember, fastest d4 in the game and a 9f combo starter, things very useful vs slow ass normals reptile
staying within his dash range is key, he can't throw out forceballs without you jumping over them for full combo punish and he can't whiff his dash anymore to get near you fast, he now has to rely on his normals, mainly D4, B1 and F2
don't whiff anything, if reptile catches you with a dash he can dash twice more to switch sides and be fullscreen
be wary of his ex forceballs whenever you make a trade with iceball vs forceball take the free slide, pushes him to the corner and the damage dealt is equal to the damage received, you win space and perhaps further a lifelead
whiffed dash=free blockstring, take the damn thing
D4 invisibility is neutral, 32 is -4 for reptile but you won't see it coming fast enough to punish it, use clone.
know when to break, take some damage if it allows you to be able to break reptile right in the corner and use ex slide if it will as well.
if you happen to jump right on top of a forceball, clone to push yourself back.
be aware that there are many ways reptile can switch sides, heres a list
Dash on hit
Ghost Dash
Throw
Forceball juggle
EX Slide note: he can whiff a slide as you jip, its safe.
