BUG: Twisted Fate can't crit after he picks a card

Rather, if the attack he fires is intended to crit, it just shows 2. . Is this intended?

Looking at the Wiki, it says

Twisted Fate chooses a magic card from his deck, and uses that for his next attack, causing bonus effects. Cast once to shuffle the deck and again to choose your card, enhancing your next attack.

It's not really bonus effects when it takes away effects that should be possible.

Step:

1. Buy Twisted Fate (Very Important)
2. Buy Crit Items and Items(doesn't matter which)
3. Use Twisted Fate's Pick a card akill and select a card(any card at all)
4. Auto an enemy. If the attack would have crit, it would just show a big 2.

Yeah I am aware that the pick a card converts his basic attack into magic damage. But why can't he crit? I mean take a look at other champions with similar magic damage modifiers - Garen Q (his auto can crit while the magic component does not), Nidalee Takedown ( even though converted to magic can crit and apply lifesteal while it does a lot of damage), Fizz Q( can apply lifesteal and spellvamp and crit also), Poppy Q (also applies crit).

It also doesn't apply lifesteal but that's kinda a different issue (although it would be awesome).
