Well, there you have it, my first attempt at wurmifying my cube (I'd be happy for some art-ninjitsu as well, my skills are still lacking there)
The red gem and scabbard-looking icon even has its exclusive animation in games such as Master Duel
Cast a Doomed Traveler, and you get a 2/2 Zombie Druid and a 1/1 Spirit for just 1 mana
Its a powerful card advantage engine, especially with cards like Mesmeric Orb that greatly increase your choices
This means that if you forget to add the life when the creature pops and remember at the end of your turn, your opponent can point to that seemingly meaningless little word on Souls Attendant and say sorry Charlie, I assumed you had a reason for choosing not to gain life
Its very useful with commanders who rely on their activated abilities, like Vorel of the Hull Clade or Oswald Fiddlebender
