I think that Dino is the healthiest +2 for the game (+1 for the destroyed monster. +2 for the drawn cards,+1 for the tribute). Tributing him early will leave you open to a probably strong attack and he is easily negateable by Mirror Force,Prison,Waboku and similar cards,keeping him away from becoming broken. I just love the most recent Duel Terminal Archetypres. Konami did a good job on these.
