Where can I find suitable animations for the new feature?

Hey guys. As the topic says, I'm looking for animations to test out the new feature with, but I'm not sure where to look. Every search I've tried has come up empty, and the two packs I can see on the marketplace don't really seem to offer what I'm looking for atm (though I'll definitely be getting the trap one in the future). At the minute, I'm looking for a sparkly, magic-y effect to signify that a specific square is a teleporter, though I'll take any suitable gifs just so that I can play with the feature. 

Bestanimations.com  claims their animations are "free", and had some disclaimer or explanation what they meant with that. I found only  one Magic spell effect gif there, but quite a few demons, mosters and so forth, some even seems usable as tokens.
