Among the three, Sobble has the strongest individual following and will probably be the pick of the region for collectors buying singles
Its an 0/3 that eventually becomes a 3/3, which blocks really well (and even attacks, if you need to)
In a color pair that only has seven planeswalker cards and for a long time Sarkhan the Mad was the best we could hope for, this card shines
Kolodin, Triumph Caster and Cloudspire Captain are possible vehicle lords you can play, and Mu Yanling, Wind Rider can take your vehicles to the skies, drawing you cards when they hit
In theory Light should have a higher ceiling and a greater range of targets
As far as a rating goes I would give this card a 4 out of 5 because it is a very powerful attacker but that is it, it doesn't have a really high hp and it doesn't have any effects to inflict on defending Pokemon, but overall I like it and I would recommend it in a fire type deck
