One of my pet cards is Chromatic Lantern, because it provides amazing mana fixing for a deck, so I have it in every one of my EDH decks, or, in the rare decks in which I do not have it, I instead have Dryad of the Ilysian Grove, as that ability is simply too useful for a multicolored deck
However, if you haven't sacrificed any Foods this turn as your end step begins, the ability won't trigger at all
Variations otherwise known as Secret Lair x Marvel's Deadpool: I Fixed it (You're Welcome) non-foil, traditional foil, and "something Deadpool calls 'Pool Party.'" Uhuh

Example: Grizzly Bears is a 2/2 creature (2 power, 2 toughness)
