Alchemy Horizons: Baldur's Gate

If there is no legal target for the reflexive trigger in Minsc & Boo's second loyalty ability, or if the target is illegal as the ability tries to resolve, you will not draw any cards even if the sacrificed creature was a Hamster.

Minsc & Boo's second loyalty ability won't deal extra damage if you shout "Go for the eyes, Boo!" but it definitely can't hurt.
