i was looking at something Dakkon had a soul sucking sword who he took as his own name the Black blade..

Umbra is the name of a sword who stole souls in the morrowind series but also controlled the user somewhat.

sounds like they might grow from a common idea any other thoughts?

mmm.. Dakkon Blackblade. That used to be my absolute favorite card. I thought it was the absolute best when I started playing. Polar Kraken? Psh. I had Dakkon and the Rune Sword artifact!

i loved my Dakkon deck spam l\\and and get super healing than pull out dakkon and be like wammo

Elric, you noob.

One word. (Or rather two combined, with one conspicuously misspelled.) Frostmourne.

Polar Kraken? Xdollars (I don't know the ammount).
Getting a Polar Kraken in your very first booster pack of magic, ever? Priceless.
