What are they?
Standard DT or Extended DT?
Before you ask, standard is only the cards with chekered background, and extended is all cards.
Standard: Berzerk Frozn Vortex Junkz
Extended: Junkz Uppers Vortex Montana All Stars
I use sentinals in standard quite well/
The Pilzken/Raven combo pretty much rules Standard DT these days...
