Kraken of the Straits | Creature | Kraken | Creatures with power less than the number of Islands you control can't block Kraken of the Straits. | Richard Wright
Tromokratis | Legendary Creature | Kraken | Tromokratis has hexproof unless it's attacking or blocking.
Tromokratis can't be blocked unless all creatures defending player controls block it. (If any creature that player controls doesn't block this creature, it can't be blocked.) | Matt Stewart
