Call of the Grave is Determination's 1st Deltarune, 3rd Common (4th if including Knife) and 9th overall Spell added in Beta 43.0. Previous Versions can be found here.
Call of the Grave (CotG) works as a mix between Tombstone for being able to summon non-duplicate Dust monsters from your Dustpile, Pre-Beta 48.1 Bloody Tree for only being able to affect Dust monster with a cost of 3 or lower, Business Dude for making them 1/1 copies instead of the actual (dead) monster and Jukebox/Father Alvin for being 3 monsters rather than 1 or 2 like the others (but are chosen randomly, which is like the others). Like Resurrection, it is also unable to give generated monsters.
This spell works very well in the deck that feature one or multiple of the previously mentioned cards (aside from Business Dude), working great in either Resurrection focused decks, Dust decks, or Plant decks (as like the old Bloody Tree, this spell works easily alongside Flowey).
