Instant
Destroy target creature. It can't be regenerated. That creature's controller creates a 3/3 green Frog Lizard creature token.

Nearly identical: 1-mana blue instant destroy giving a 3/3 token.

Cheap blue removal exiling a creature, replaced by manifest.

Universal removal giving opponent a 3/3 token, same effect template.

White version destroying any permanent for a 3/3 Elephant.

Blue exile removal replacing creatures with 2/2 Boars.

Two-mana blue version making a 4/4 token, artifact/creature targeting.

No—instead, Ravenform exiles target as cheap blue removal with a bird token.
If Rapid Hybridization resolves and the creature isn't destroyed (perhaps because it has indestructible), its controller will still get the Frog Lizard token.
If the creature is an illegal target when Rapid Hybridization tries to resolve, it won't resolve and none of its effects will happen. No Frog Lizard token will be created.
