"Baby Dragon" you control cannot be targeted for an attack while you control a Dragon monster with a different name. (Once per turn): You can Special Summon 1 Level 4 or lower Dragon monster from your hand. If you would Summon a Normal monster with this effect, you can Summon it from your GY, also the first time it would be destroyed each turn it is not destroyed.
Legendary Quest
During your Standby Phase, if you control a “Baby Dragon”, you can tribute it to Special Summon “Thousand Dragon” from your Extra Deck, also, for the rest of the Duel, you can Special Summon “Thousand Dragon” by tributing 1 “Baby Dragon” and discarding 1 Level 7 or higher Dragon monster (both of these effects are treated as a Fusion Summon).
Legendary Relic
(Once per turn): During the Standby Phase, you can have all "Thousand Dragon" you control gain 1 Millennium Counter (monsters with a Millennium Counter gain 300 ATK). You can remove 1 Millennium Counter from "Thousand Dragon" to Normal Summon 1 Dragon monster and place 1 Millennium Counter on it.
