Riptide Shapeshifter ability search for drake find changeling I dont want rulings mtg

[killarobot]

If I activate the ability of a Riptide Shapeshifter to search my library for a drake

and lets say I start revealing cards from the top of my library and I reveal a Turtleshell Changeling which I dont want right now. Can I say the turtle is not a drake (since it is all creature types then its also creature types that are NOT drake) and keep revealing cards until I find a real drake?

[Arix]

No. The Changeling is a Drake, and you can't not get it just because you don't like it. Since you've revealed a Drake, you stop revealing and put the Changeling into play.

because a changeling is also a goblin and a dwarf and a elemental and a soldier and a elf and a giant and many other types that are not drake and for example elf is not drake so you skip it so I figure since its more types that are not drake then maybe I could say its one of the other types?

[Rocket]

what matters is that its also drake, thats why it satisfies the condition of the riptide shapeshifter

because a changeling is also a goblin and a dwarf and a elemental and a soldier and a elf and a giant...

phew you stopped I thought you were gonna list all of the creature types
