Duel deck ideas

Lujikul

I’m thinking of practicing my deck building by making various budget duel deck themes ($20~$30 a deck) and then squaring them off with friends. However, I am somewhat uncreative and the only one I’ve come up with so far is Gisa vs Geralf. I’d do Vampires vs Werewolves but werewolf cards are weirdly expensive. If any of you have ideas you’re willing to share, it’s be much appreciated!

Eldrazi vs Slivers! People said that the eldraz would win but I think the swarm would win

I am going to think of some more for you. Could you tell me the deck compositions so that I can make them too?

Some of these, cool as they are, I'm having to pass on due to budget restraints.
First one I'll be doing is hounds vs cats. (This post'll be edited to include the lists.)
