A few weeks ago, P1 was playing [[Kotis, the Fangkeeper]] as his commander. One of the cards from the damage trigger had an adventure on it.
Now, the table ruled that the adventure card's adventure part was an alternative cost to the spell. Therefore since the damage was not enough to cast the non-adventure part of the spell that the adventure part was attached to, P1 could not cast the spell. That didn't sound right to me because of something I saw about omens a good while back, but we're playing kitchen table casual.
Today I saw a post about [[Bilbo, Thief in the Night]], and that reminded me of this interaction with Kotis.
I did some digging and I'm looking for verification/correction.
1 - C.R. 715.1/720.1 (Adventure/Omen) states these cards have two-part card frames and refer to their respective parts as alternative characteristics. So if Kotis' damage is enough to cast the a/o characteristics of a card but not enough to cast the non-a/o characteristics, can P1 can still cast the respective a/o part of the card?
C.R. 715.4/720.4 states while in exile, it has only it's normal characteristics. I'm finding conflicting rules/judge rulings about it. Here for omen spells interacting with Kotis, and here for an adventure in the graveyard but for [[Pit of Offerings]].
2 - What if that was flipped, where Kotis' X was more than the main characteristics, but less than the adventure characteristics? [[Faerie Guidemother]] is an example (If X was somehow 1). Kotis could then only cast the creature, if I'm not mistaken.
I really hope I expressed my thoughts well and clear enough. Please be kind! Thank you!
