The biggest issue here is that Krark, the Thumbless has an ability that flips coins, but doesnt really care about other cards doing the same, so ultimately, it isnt that ideal as a coin flip commander but rather as a spellslinging one
While this card can only be Normal Summoned by Tributing a normal monster, you can use its quick effect to get it on the field during your opponents turn
Function: Punisher[/spoiler] [spoiler='Oceanbound Weapon'] [spoiler='Lore'] When this card is Summoned: You can send up to 2 "Oceanbound" monsters from your Deck to the Graveyard
