Flicker Evasion is a use of speed. The Third Raikage had the same technique as his his son the Fourth, lightning armor, which augments the speed of the user exponentially. In the case of the Raikage, Jinchuuriki, and EIG users I believe, their flicker evasion doesn't require any chakra, it's simply them moving at their base speed. Though, for Minato and Tobirama it takes chakra.

(Bodi-en no Jutsu) Ninjutsu: Body Flame Technique
Type: Supplementary
Rank: B-Rank
Range: Short-Long
Chakra: 20
Damage: N/A
Description:
This technique is used in a similar way to the Body Flicker Technique. When using this technique, the body appears like it's being engulfed by flames, disappearing from view slowly, masking the users own high speed movement. In essence, the technique is simply an elemental variation of Body Flicker technique and thereby follows the same restrictions and possible uses.
difference between the first and second technique is that the user dissolves in flames but it's assumed that the user has moved before their body completely goes up in flames considering how slow the flames dissolves their body. The substitution technique actually is much like the body flicker, difference, the with the latter you're only moving at high speed and with the substitution you're mixing high speed with the transformation technique to transform a dummy.
questions, if not we'll finish up this method with the last set of techniques.
