4 rulings from Wizards of the Coast
- 23 July 2021The fight happens in the declare attackers step before blockers are declared. Unless the creature it is fighting survives, that creature won't be able to block that combat.
- 23 July 2021If a player casts a spell that targets multiple permanents their opponent controls with ward, each of those ward abilities will trigger. If that player doesn't pay for all of them, the spell will be countered.
- 23 July 2021The Tarrasque will have haste and ward {10} even if it was cast from a zone other than your hand. May we suggest the command zone?
- 23 July 2021Fighting is not optional. If there is at least one legal target for The Tarrasque's last ability, it must fight.
