Forum:Alien Support Cards

I'm making an Alien deck, and I have it almost complete. However, I was wondering whether I should add in, as support/trump card/final resort, Evil Dragon Ananta, or Vennominon the King of Poisonous Snakes. I like Vennominon because of it's special summoning mechanic and that it leaves my cards in the graveyard so I can swarm, but I also like Ananta because I can special summon it from my hand, and it generally has more ATK than Vennominon. Which card should I add?
