Ursine Monstrosity
Creature — Bear Mutant
3/3
Trample
At the beginning of combat on your turn, mill a card and choose an opponent at random. This creature attacks that player this combat if able. Until end of turn, this creature gains indestructible and gets +1/+1 for each card type among cards in your graveyard.
Rulings
- If you can't mill a card, you'll still follow the rest of the instructions of Ursine Monstrosity's last ability.
- Ursine Monstrosity must attack the chosen player if able, not a planeswalker they control or a battle they protect.
- If, during your declare attackers step, Ursine Monstrosity is tapped, is affected by a spell or ability that says it can't attack, or hasn't been under your control continuously since your turn began (and doesn't have haste), then it doesn't attack. If there's a cost associated with having Ursine Monstrosity attack the chosen player, you aren't forced to pay that cost, so it doesn't have to attack that player in that case either.
- If Ursine Monstrosity isn't forced to attack the chosen player for one of the above reasons but can still attack, you may choose to have it attack another player, a planeswalker, a battle, or nothing at all.
- If your turn has multiple combat phases, Ursine Monstrosity's last ability triggers at the beginning of each of them. Ignore any choices made for its last ability during previous combat phases.
- The card types in Magic include artifact, battle, creature, enchantment, instant, kindred, land, planeswalker, and sorcery. Legendary, basic, and snow are supertypes, not card types; Horror and Room are subtypes, not card types.
