When the card Assassin's Trophy was first spoiled, my first thoughts was "An instant Sinkhole!", and since then I have wanted to make a Mana Denial deck, the core of the deck being:
4 Deathrite Shaman
4 Abrupt Decay
4 Assassin's Trophy
4 Null Rod
From there, where would you go? Blue for stifle, power, counters, and leovold? White for Thalia, and Stony Silence, Swords? Should it include Chains of Mepho? Or would you go a different route with this set core? Just spitballing ideas I've had and seeing where other's would go with it.
