This cards effect originally stated that if it was in the graveyard during your standby phase, you could add it back to your hand
return it to the hand, and if you do, place up to 2 face-up "D/D" Pendulum Monsters from your Extra Deck in your Pendulum Zones, but they cannot activate their Pendulum Effects this turn
If this monster is in the Extra Monster Zone, you can Tribute a monster to return a card to the hand which bypasses almost all protection effects
if you do, when that creature enters, you'll create a 1/1 token copy of it
HP values vary significantly, with basic Pokmon typically having lower HP (as low as 30 HP), while evolved forms, EX, GX, and VMAX Pokmon can reach significantly higher HP values (up to 340 HP)
