You can also use "Star Blast" since it costs the same amount of Life Points to make this card summonable.
Using "Gilasaurus" as tribute fodder is also a good idea; your opponent will summon an additional card to be banished, 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.
Set "Xyz Dimension Splash" before you summon this card. Upon summoning it, this card will banish it, activating its effect and summoning 2 Level 8 WATER-type monsters to the field, and then Xyz summon for a Rank 8 monster that requires 2 or 3 Xyz monsters for an easy OTK. (most easily achievable with "Megamorph" and "Neo Galaxy-Eyes Photon Dragon")
