Rule 702.73a
Official source text from the 25 January 2019 Rules release
Evoke represents two abilities: a static ability that functions in any zone from which the card with evoke can be cast and a triggered ability that functions on the battlefield. "Evoke [cost]" means "You may cast this card by paying [cost] rather than paying its mana cost" and "When this permanent enters the battlefield, if its evoke cost was paid, its controller sacrifices it." Paying a card's evoke cost follows the rules for paying alternative costs in rules 601.2b and 601.2f-h.
