This is totally a matter of personal preference and how you use your cards. If you have an abundance of continuous traps, Uria will be very useful. However, if you are in possession of a Crystal Beast deck, Rainbow Dragon will(obviously)be more useful.
No, Uria, Lord of Searing Flames is a Pyro-type monster.
"The Winged Dragon of Ra", "Slifer the Sky Dragon", "Obelisk the Tormentor", "Hamon, Lord of the Striking Thunder", ("Uria"), "Raviel, Lord of Phantasms"
Well slifer I'd think as his effect is that his atk points rise by 1000 for each card in your hand but you have to tribute 3 monsters for uria his atk rises by 1000 for each continuous trap in your grave and you only need to tribute 3 traps
Rainbow Neos is a fusion of Elemental Hero Neos, and either Rainbow Dragon, or Rainbow Dark Dragon.
Uria lord of searing flames and Ra the sun dragon.
depends on how you put together your deck or who your opponent is. if you have dark types in your deck,graveyard,and field, then i suggest rainbow dark dragon but you will not gain as much attack as rainbow dragon.although rainbow dragon gives you a lot of attack, there is not as much cards available to gain the attack and..... its complicated so ill just get to the point, they are the same if you have a regular deck that is not focused on certain monsters so like i said, depends on how you put your deck together.
You make it with rares i got rainbow dragon by breeding Gummy dragon and Soccer Dragon.
The card number for "Rainbow Dragon" is 79856792.
