As much as I'd like to agree with you, I can't. Myth will not get a spell like fuel. Our main thing is not DoT spells. We specialize in a variety. I would be glad to see something sort of like that though maybe a double trap so we don't have to spend time for orthrus or minotaur or future spells. I don't know :P
There is a pet version of this card from the level 98 hybrid between Sun Serpent (Fire) and Medusa (Myth). It would be a welcome addition as a learned spell though. It might make me actually use some of Myth's spells other than Frog and Pigs, but I doubt it.
