This is the legendary Rainbow Dragon. Discuss it Here.
Post pros, cons, weaknesses, strengths or anything related to it (including its dark counterpart {Animé or real life} and Crystal Beasts)
my opinion
PROS: Extremely High ATK. Great first effect. Max ATK is 11000 (wow) which can run over almost every card in the game.
CONS: 0 DEF. Second effect is pretty useless. Very Hard to get out.
ill give it a 7/10.
