I split it with UD for Ruby Crawlers and phoenix birds. They hold out well enough to set up the board. I've never really been a top 10 player anyway so I just play things for fun.
Yeah I haven't tried them with ruby crawlers, but phoenix is a staple of the deck for sure. The incarnation I play revolves around powerturns with flame surge on the board combined with imp familiar's flame charge and transfusion to create a boardwipe. Cool when it works, but it usually doesn't work at high ranks. Definitely a "for fun only" type of deck
