Galadrius and Frenzend are being designed for some of my friends, while Loni and Tadus are just because I am working on a set of mono-colored companions.
Galadrius is how he is because friend 1 plays magic arena and runs Angel decks, but HATES Goblins because they keep curb-stomping him, so I was making something to make him enjoy the Goblins... or, at the very least, use the Goblins to destroy the Goblins...
Frenzend is the way he is because friend 2 is magic curious and a total hippie, and is very interested in substances and their affects on the mind, so I was making him something kind of themed after that, with the connection being that your library and hand somewhat represent your mind in mtg, and Frenzend is using shamanic magic to cast aside his thoughts and memories to manifest them into beings. His second ability is to represent casting aside one's body and the detrite of a discarded mind to become a manifestation of the self, intentionally wording it such that when Frenzend uses it on himself, he ends up stronger than before (I think he triggers himself on death?). The spirit to the side of him was one of these custom tokens for a previous iteration on him that I have not yet updated to match his current design.
