The hardest part was having to get used to the way acrylics work >< I've never touched the things before. Only painting experience I had was watercolor.
Acryllic is the easiest physical medium in the world once you get used to them.
Honestly I feel like they are a bad medium for magic altering since you want to keep the cards flat. when I alter I don't play with the alters so I tend to lay it on thick like the medium is good at doing. I mean it CAN be used for flat painting too. Just not as good as oil. Just 1,000x easier, cheaper and faster to work with than oils. Fuck oils.
This one is actually still pretty flat. I can't honestly feel it through the deck sleeve it's in. However, I can see how with other, more colorful projects, it could pile up.
In Yu-Gi-Oh! terms? Any creature except a DARK-type creature.
In Magic you can't just play whatever card you want. You are limited by colors of mana. So if I want to use this Doomblade card, I have to be able to produce Black mana. Thus, black decks can use this to destroy creatures. Other colors cannot automatically just destroy any creature they want. But they can do other things better than Black.
Also: Altering cards is illegal in yugioh tournament play. Its legal in Magic.
Someone at game day today saw the apostle I had done and requested that I alter the art on this sol ring to make up the difference in a trade. not terribly complicated, but I'm happy with how clean it looks.
