Hi,I have a question regarding the ruling of Final of Promise (haven't played magic in a while so I'm rusty.
Regarding hybrid cards, can you target for example the "Carnival" part of "Canival/Carnage" (since there is a sorcery in the double card) plus for example "Shock" (an instant)? My guess is no, but I remember in Modern there were some shenanigans with some double cards which doing some tricks you could cast the "expensive part" of a double card by only paying the mana for the cheap one.
Cause I've been looking and there aren't really any good 1 mana sorceries in standard, right? Opt, shock, etc are all instants. So maybe Final of Promise will be really good only from 4+ mana on, to cast two 2-mana spells?
For the purposes of Finale of Promise, a split card (not: "double card" or "hybrid card") in your graveyard has the combined mana costs and combined card types of its two halves (C.R. 708.4, 708.4b, 400.1), and that card's "mana value [is] determined from its combined mana cost" (C.R. 708.4b). Thus, for example, Carnival & Carnage in your graveyard is an instant sorcery card with combined mana cost 2(B/R)BR, making that card's mana value 5 (not 4 and not 1) while that card is in your graveyard (C.R. 202.3, 202.3f). As a result, if you cast Finale of Promise and choose 5 or greater for X, you can target Carnival & Carnage as the "target instant card ... [in] your graveyard ... with mana value X or less" or the "target sorcery card [in] your graveyard ... with mana value X or less" (C.R. 603.2b-c), so that you may cast either half of that card when Finale of Promise resolves (C.R. 708.3).
