You can point this at an opponent's monster, declare a new Attribute or Type for them, and use it against them.
If the opponent's monster is Level 4 or lower, declare Dinosaur and then destroy it to activate the second effect of "Souleating Oviraptor".
Declare the appropriate type for the control-switching effects of "Electric Virus", "Marionette Mite" or "Puppet Plant", then use that monster and this card to go into a Link 3 Link Monster.
Declare Plant, then use "Fragrance Storm" to destroy the opponent's monster and draw some cards.
Declare LIGHT, then equip the opponent's monster to "Dark Blade the Captain of the Evil World".
