Blade Flurry is a nice card in general, a Pirate theme doesn't really mean anything, considering a single pirate card buffs your weapon. Poison Dagger does wonders with it and spell damage also affects it.
Fan of Knives is pretty weak outside a spell damage deck, and Betrayal is good overall.
Betrayal is very solid vs aggro/swarm decks - I'm still on the fence about the card in general since it is absolutely useless vs 1 minion and I'm not a big fan of situational cards.
I quite like Fan of Knives a lot, even in a non pure spellpower deck (though incedental spellpower makes it even better aka Azure DrakeBloodmage Thalnos) Cantrips and cycling are fantastic - "Draw a Card" the best 3 words you can see on a card imo. :)
Fan of Knives vs. Blade Flurry vs. Betrayal
Which of these cards do you prefer to use against minion swarms, and why?
It very much depends on the deck you are using.
If you are using a Pirate, Weapon deck, Blade Flurry would be the best
Fan of Knives is good in Rogue spell damage decks as it becomes a 2/3 damage AOE, instead of 1
Betrayal is a pretty good overall good ability

You're not going crazy, I edit 2~3 times each post
Blade Flurry is a solid card if you're playing with Assassin's Blade or Deadly Poison...if you aren't it's really useless.
