KMS U-110

Submerge (This creature can't be blocked except by creatures with submerge.)

Whenever KMS U-110 deals combat damage to a player, look at the top three cards of that player’s library. You may exile one of those cards with a code counter on it. Put the rest on the top of that player’s library in any order.
You may play exiled cards with code counters, and you may spend mana as though it were mana of any color to cast
them.
