Essentially, if you have a full party with all four of these on the board, you can pay one white, one blue, and one black mana to give the Warrior lifelink, deathtouch, and make him unblockable (deathtouch and unblockable at the same time has no real use, but thats still OP to think about)
Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to a creature may become lethal if you switch its power and toughness during that turn

In 1998, to convince Nintendo that Pokmon could work in the English-language market and to try and win the rights in that territory, Wizards of the Coast commissioned a "presentation" card featuring the Water-type Pokmon Blastoise
Together with being only handed over for this event, Konami also made this card very rare by printing only 126 copies of it initially making this one of the rarest Yu-Gi-Oh cards
It doesnt matter what happens to that Assassin or commander after that
