dat Morte is a scary one... :p
He sure is.
When viewing this card one cannot see the top of it so it very well may be a spear.
True. But I started to picture Arsenic as a dagger, so it's kinda stuck with me. For me, it just fit the theme. After all, you don't
usually poison spears. Dagger, darts, sometimes arrows, but almost never spears or talons.
Leviathan would look cool as a sea-snake or something. If he's made up (iirc he is), here's a deck idea for him:
I didn't want it to be water/air because that's what Neptune is, so I made it a mono-water NT rush (Yes, I know AI doesn't like using NT on water pillars/pends).
Well, You weren't wrong, Leviathan is a sea-snake, and he is made up. But, the deck is already set. And, to be honest, the deck you suggested doesn't really look like something Leviathan would use. Looks like, I don't know, a mermaid-FG? Maybe nereid-FG? But not a leviathan. Deck is good, don't get me wrong. It just doesn't fit the theme.
