What should be the most commom formation used by Strange players is, in the corner, ground level 1R(1), jump height 1Y(2).
The first number indicates how many of the graces should be in that spot (some formations group graces together), the letter indicates the color, the (number) indicates the preferred order of deployment. This actually matters. You should probably always deploy red graces first.
So it should look like your red grace is overlapping your opponent, and the yellow grace is directly above them. This is a very good formation.
The main use of this formation is to apply mad corner pressure. As long as you’re on the ground, the flame will be directed to the red grace on the ground. You want this. This way, the opponent can not duck under the flame, and you can cancel anything into flame and give yourself frame advantage. Assuming you position the red grace well, you also get access to your throw game, since you can use the red grace to OTG after a throw. This formation also gives you 2 extra combo extensions if you land an odd hit.
The yellow grace comes into play when the opponent escapes. If they super jump away, or otherwise don’t get hit by the flame, the flame will go from the red grace to the yellow, and you will still maintain advantage. You can also access the yellow grace immediately by jumping and throwing the flame. This will usually guarantee your advantage.
But really, you just need to exploit Flames a lot. When you have a red grace on or behind your opponent, just spam it. It’ll hit them and you’ll be super plus.
Midscreen, I usually just group yellows, or make a linear formation of yellows and play off that. I’ll have to define more formations.
Now, mid flight modification is hard because it requires a triangular formation, and you have to throw the flame far away from the first grace. It’s also really situational and I only had it become relevant in one match personally. I’ll have to explain it in the tutorial because it’s kind of complicated. But basically, if you had 3 graces out, and you throw a flame, and create a new grace before the flame reaches the first grace, you can do some cool shit.
