mtg pay life cards Rules Text: Pay, 1, life, 264 MTG Top 10: Cards You

The Beast on the Playmat is a stone version that looks much like a traditional Gargoyle

We can derive it from this section of the CR: 601.2g If the total cost includes a mana payment, the player then has a chance to activate mana abilities (see rule 605, Mana Abilities)

A close second is White, with just three: Shahrazad (which creates a game-within-a-game situation), Limited Resources (which usually destroys lands and makes players unable to put new ones out), and Balance, the most cost efficient board wipe ever made
