Owl kind of sucks, but sometimes you really need to access a fusion card and if you run 1 Owl that means you can access Polymerization or some form of standard fusion device with at least belated searching using literally 20 cards from your deck
have as small a deck as legally possible
So this is annoying when they want to start a play with Reino or Diviner, and it also negates their omnis (Toad and Baronne) but now you need to do something with that 3500 ATK Kaleido-Heart while your monsters have -500 ATK
Side Deck 15 Fishborg Harpooner X WATER Level 4 [ Fish / TunerEffect ] ATK 400 DEF 400 You can reveal this card and 1 WATER monster in your hand
So, there really is no wrong choice here
