Minsc & Boo, Timeless Heroes

When Minsc & Boo enters 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 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.
