You probably have seen the PVP Graboid Rainbow. This deck is very similar, with Horned Frogs replacing the Forest Spirits (bad I think, since Forest Spirits provide more offense), two Purifies replacing two Deflagrations (bad, the deck now lacks PC), and a Blessing replacing a Freeze (some, like me, replace this with a Vampire Stiletto, but I think overall it's not a good substitute). I think it would be slightly better if you replaced the five cards from PVP Grabbow with something like two Fire Spirits (never tried it, maybe it works), 2 adrenalines and a blue crawler?
