Titanosaurus

This eponymous, dubious genus of Titanosaurid was created by Clockwork.

Nomen Dubium
This card can not be targetted by Prehistoric cards.

Collapse
All other cards on the field are destroyed when this card is played. This card gains the elements of each destroyed card. Any card that shares its element with this card can not be played.

Inner Core
This powerful attack has no secondary effects.

Origin Information
Titanosaurus indicus is the type species of the genus that gave its name to Titanosauria. Like the rest of the species in this wastebasket taxon, it is considered dubious; other species, like the well known T. colberti, have become genera in and of themselves (in this case, Isisaurus), while others, such as T. blandfordi, have too little material to assign any classification.

Using Titanosaurus
Time the moment that Titanosaurus is played for optimal attribute coverage. If your enemy has a single Ankylosaurus on their field, then great, you took care of it; but if you both have 1-2 dual attributed cards, then you've just crippled them, preventing multiple elements from being used. In any case, Earth elements are done for; as soon as Titanosaurus hits the field, all ankylosaurids and large sauropods, as well as many other large creatures, are permanently out of the game.

Of particular note, Missingno. and Titanosaurus make a horrifying, game-breaking combination.

Defending against Titanosaurus
Though Collapse can cripple a foe's playable cards, it can also cripple the user's. If you know he has Tyrannosaurus in his hand, then just make sure a Fire attribute is on the field when Titanosaurus gets played, and you don't have to worry about it anymore. Otherwise, try and keep as few cards of as few attributes on the field as you can, limiting the destructive capabilities of Collapse, after which Titanosaurus has little power.

Trivia

 * Collapse is based on Titanosaurus's size. Though it is the namesake of the giant Titanosaurs, Titanosaurus itself was estimated to have a relatively small length of 30-40 feet. The mental image of a breath-takingly enormous, 300+ foot sauropod condensing itself to Titanosaurus's actual length inspired Clockwork to continue the trend, shrinking it further and leading his mind to Black Holes.
