Creature — Kraken
6 / 6
Trample, ward
At the beginning of each combat, if Reservoir Kraken is untapped, any opponent may tap an untapped creature they control. If they do, tap Reservoir Kraken and create a 1/1 blue Fish creature token with "This creature can't be blocked."
Players won't know which player or planeswalker Reservoir Kraken will attack, if any, when deciding whether to tap an untapped creature for its triggered ability.
