Forum:OTK with Naturia Cliff?

I have activated "Gaia Power" and "Des Counterblow", and I attack directly to my opponent with "Naturia Cliff", then I can special summon another "Naturia Cliff" and attack again, then I can special summon another "Naturia Cliff" and attack again, and finally I can special summon another "Naturia" monster and win the duel.

Is it possible?
