By the time your enemies are casting Consecrated Sphinxes and other bombs, you should easily have enough lands to effectively make this a Terminate
Another great creature land, this one becomes a beefy creature that can either load your graveyard or threaten to mill out your opponent The creature might not be quite as impressive as the others, but the fact it can buff something else generally means it can open up a good attack for another creature too This creatures hard to block and lets you rummage
What ProxyMTG is not (so you dont buy the wrong thing) Lets do the responsible part
Akromas Will is one I really like in decks that go reasonably wide with creatures that have decent base power
Pick a theme, then for every card you're considering, ask yourself, "does this card support my theme?" If not, then you can safely cut it
Even better, when creatures your opponents control attack other opponents, their power gets doubled, meaning that this creature turns board states into potential game-ending situations
