jiggly puff pokemon card - Jigglypuff (65/124) Common Card Type Jigglypuff 198 - Holofoil SV

Being able to cast creature cards from the top of your library is already strong, and you can cheat big creatures into play once per turn, and not just from your hand in a clunky way like Elvish Piper does

Before anyone asks, yes, this deck is decent and probably the best strategy in the OP15 set

A creature that follows in the footsteps of "Experiment One," but since it grows based on the mana spent, it's easy to grow it by one at a time, but hard to grow it all at once

If a spell or ability's effect has other parts that don't depend on searching for or finding cards, they will still work normally

It's because they can also put you at a disadvantage if you use them too often
