Like most Pokmon cards, the value of Regigigas depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Legends Awakened)
Think about cards like Malcom, Keen-Eyed Navigator or Storm the Vault that generate Treasures whenever your creatures deal combat damage
You can also cast Zacama, Primal Calamity on the cheap and still untap all of your lands to have access to even more mana to use to cast Dinosaurs or activate Zacamas abilities
(2023-02-04) Effects that modify a creature's power and/or toughness, such as the one created by Blazing Crescendo or a +1/+1 counter, will apply to the creature no matter when they started to take effect
