>>33943598As a boosting move it's not as good as others. Firstly it's only +1, which means you have to hit twice to outspeed scarfers that have more base speed than you, sometimes even 3 times for fast scarfers, where agility and it's clones are +2 per turn so you save up on turns to set up.
Secondly it does contact damage, which adds a risk of losing your momentum due to Rocky helmet and other contact triggered abilities.
It doesn't help that it's only 50 bp, but a +2 boost with 20 bp would make it somewhat viable.
As it is now, you'll be lucky to get 1 flame charge off before they go to something that can counter you, and at that point you would have been better off with a scarf.
