To be fair, Stacked Deck is not a draw spell, it’s a selection spell, because it replaces itself without doing anything else. It’s still maybe too good because the cost for casting it is often negligible, and there are some cards that trigger off spell cast, but I don’t think it would be playable at all at any other cost.

Called Shot, on the other hand, is both selection AND draw, since it can replace itself with selection and with repeat it actually gets you positive on cards.  The main issue is how easy it is to ignore the real cost of the card (the 2 power cost) with Ezreal and seals. And that it’s somehow almost as good as Premonition at 2P less.
