So far, all "Gandora" monsters have a nuking effect followed by an ATK gain, and the downside of halving the player's own LP.
Since the nuking effect of "Gandora Giga Rays the Dragon of Destruction" becomes more potent the more unique "Gandora" monsters in the Graveyard, using cards like "Foolish Burial" or "Trade-In" helps with consistency and power simultaneously.
Note that even if cards like "Macro Cosmos" help you to increase the ATK of "Gandora Giga Rays", they aren't recommended because they also prevent you from Special Summoning it.
