The only three cards that "remove" a creature are Reverse Time , Eternity (ironically has good sync with ), and chimera. All other cards technically kill the creature.
Technically, Chimera doesn't "remove" it from the field. Actually, all cards become part of the Chimera, that's why the combined attack/hp.
I see "remove" as TAKING IT off of the field to SOMEWHERE ELSE, as your hand, your deck or to the 5th dimmension.
Maybe you could change the passive's name. "Heavy" doesn't sound that good to me, because most people already see it as high hp... I guess we can get used, but I'd prefer a name change...
I would make it something like sturdy, or hefty or just for laughs "Wideload"
