I initially made this deck as I needed a deck with Yellow and Red for the achievements (my least played colours), but it is ending up as one of the better decks so far! Basically it's a control build with a Boneyard Abomination OTK to finish games. This is not anything new in itself, but I feel that the combination with red is super nice. Basically it allows for two activators for Boneyard Abomination (Volition and Dashing Ringmaster), which can even double (for only 9 mana total). Plus the red package adds some tempo and early game defence (trapezists), card draw (Muse, Bull, Oak), heal (Extract Life) and removal (Gigantomachia and Magmataur). Then later game Yellow takes over with all their control tools. The green package is super sweet, born again is a great recurring roadblock to stall and save some face damage and the bald mountain is great value to reuse card draw, removal or healing tools.
Some small comments to consider when trying:
