You can only activate 1 card with this card’s name per turn.
(1) When a monster effect is activated and you control a “Dinomorphia” card: Pay half your LP; any battle damage you take for the rest of this turn becomes half your LP at the time you would take it, also negate the activation, and if you do, destroy that monster.
(2) During damage calculation while your LP are 2000 or less, if you would take battle damage: You can banish this card from your GY; you take no battle damage from that battle.
