Strago and Relm [FINAL FANTASY Commander]

Sketch and Lore—{2}{R},{T}: Target opponent exiles cards from the top of their library until they exile an instant, sorcery, or creature card. You can cast this card without paying its mana cost. If you cast a creature spell this way, it gains haste and "At the beginning of the end step, sacrifice this creature." Activate only as a sorcery.
