What it does
Sleight of Hand isn't a keyword ability—it's a classic blue card-selection instant (or sorcery, depending on printing; the original is a sorcery). When you cast it, you look at the top two cards of your library, put one into your hand, and exile the other. It's a cheap one-mana way to dig toward what you need.
The common misunderstanding is that it draws or filters more deeply—it doesn't. You only see two cards and keep one, so it's selection, not card advantage. The exiled card is gone, not bottomed, which matters for shuffle effects, graveyard recursion, or anything that cares about exile.
In Commander, it's a fine but modest cantrip-style filterer. With 99-card singleton decks and bigger life totals, raw card advantage often outclasses thin selection, so Sleight of Hand sees less play here than in 60-card formats.
