Twitsed Fate - Pick a Card + Runnan's Hurricane Bug ( Big nerf to ADC TF )

Did throwing the Pick-a-card card ever (in previous patches) cause Runnan's to fire the extra bolts?

Well, I don't believe this is a bug, more of an inadequately explained interaction. When I've played TF, if I remember correctly, when you actually throw the Pick-a-Card card, there is a very brief channeling/progress bar near the bottom of the screen like you get for other channeled abilities; this leads me to think it is considered more of a spell than an autoattack, a spell that adds one stack (or procs) his Stacked Deck, applies Lich Bane bonus damage, etc... many of the things an autoattack would do, but it isn't actually an autoattack. After all, it can't crit, can it?

I just had a thought: if you have the Spell Weaving and Blade Weaving masteries, which buff does throwing a Pick-a-Card card at a champion give you?

Uhh but hurricane =/= stacked deck. Bad combo.

The reason that is is because the stacked deck proc will sometimes hit on initial attack or one of the hurricane arrows. It's a pattern because it counts the two hurricane arrows as follow up attacks for stacked deck but it's extremely unreliable to get the damage on the intended target unless you're a really good player at remember the pattern in which they proc stacked deck.

It's because Twisted Fate's PAC-empowered auto attack isn't actually an auto attack for the purposes of mechanics and calculations; it's a spell. It's the same reason why Pantheon's passive doesn't block it and Jax' counterstrike doesn't dodge it. I'm pretty sure it isn't stopped by blinds, as well.

Depending on how some people play ADC TF, Runnans is a decent item. It procs your E every other auto which adds a lot of mixed damage.

Anyways, picking a card throws out a single attack instead of the Runnans attack with the bolts.

• Pick a card - Active: When first activated, cards flash over Twisted Fate's head in the following order: blue, then red, then gold (this cycle repeats itself). When he uses the ability again, he picks the current card over his head; **the card picked converts his next basic attack within 6 seconds to deal magic damage and add a special effect**. Twisted Fate has 6 seconds to select a card.
  

• Runnan's Hurricane - **Your basic attacks fire minor bolts at 2 nearby targets, each dealing 10 (+ 50% AD) physical damage and applying on-hit effects.
  

** So what this does is ruin your DPS by picking a card since you will proc E less often.

TL;DR: Picking card makes Runnan's Bolts not work for that Auto

Working as intended. Pick A Card is basically a unique attack modifier, meaning that it can only apply to one attack.
