You can also use Star Blast since it costs the same amount of Life Points to make Gandora summonable.
Using Gilasaurus as tribute fodder is also a good idea; your opponent will summon an additional card to be removed from play, which would otherwise be disadvantegous.
This card works fairly well in a Macro Deck. You can use it's effect while you control "D.D. Survivor" and/or "D.D. Scout Plane". This cards effect will Banish then, which means they will return to the field during the End Phase.
You can use "Dimensionhole" to Banish this card then have it come back later on to use its effect again, or even as Tribute fodder.
This cards effect can trigger your own "Starlight Road", albeit at a hefty cost.
Use this card with "Future Visions" to dodge the self-destruct effect.
In a Dragon Deck, you can tribute summon this card to remove from play all monsters on your opponent's field, then remove it from play for "Red-Eyes Darkness Metal Dragon". Then you can use "Red-Eyes Darkness Metal Dragon"'s effect to special summon another Dragon for two direct hits.
