D/D/D, or Different Dimension Demons, is a favourite deck of mine (one that I used to KOG with before I worked out how to submit things on this site, which, I must confess, was very recent lmao), and one that was meta some time ago but has largely been lost to the sands of DL history

Posthumous Army Can be used each time your Lifepoints decrease by 1000
