Randiss, Oozing Biomass

Swampwalk, protection from artifacts
Whenever a land enters the battlefield under your control, you may gain two life.
Whenever an opponent attacks with one or more creatures, you and that player each create a 0/1 Black Ooze creature token except your token has "protection from tokens".
Players can't attack you unless they pay two life for each other Ooze you control.
