Oh goodie, someone wants to discuss Tigrar.
Tigrar Fury versus Mournful is a good example of counter zoning with tigrar. The speed and hitbox of it is perfect for knocking Kitana out of air glaives and since he heavily outdamages her in the fireball game, if he hits her out of it, he gets a major zoning advantage. You make her come in and she'll be in a lot of trouble. If you were more specific I'd be able to give a more nuanced explanation. How Tigrar counter zones is different depending on who he's fighting. There's no real flow chart to it.
For example, low fireballs might be good against people with low profiling fireballs cause he'll hit them, trade, knock them down and potentially get in range to attack up close or get zoning advantage.
Low fireballs are good because at a range they punish people for neutral ducking your fireballs and at several ranges and for a bar can launch for pretty hearty damage (30% is very feasible).
Flame breath is actually hilariously good for oki in a couple scenarios like at Summer Jam I was playing this Kung Lao player and was using flame breath at a range to beat out spin and ex spin because of its incredible range. This is effective against a lot of wake ups although advancing ones are in many cases an exception. Aside from that, most of your oki is universal with armor, back 3, 3, down 3 etc.
The movement is basically the same, this question is a bit too vague in my opinion. For the characters you have to get in on, it's the same general strategy as it would be for Kuatan or Dragon Fangs. Gotta be patient.
