When Minsc & Boo, Timeless Heroes enters the battlefield and at the beginning of your upkeep, you may create Boo, a legendary 1/1 red Hamster creature token with trample and haste.
[+1]: Put three +1/+1 counters on up to one target creature with trample or haste.
[−2]: Sacrifice a creature. When you do, Minsc & Boo, Timeless Heroes deals X damage to any target, where X is that creature's power. If the sacrificed creature was a Hamster, draw X cards.
Minsc & Boo, Timeless Heroes can be your commander.
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.
