You take out a land, then capitalize on your opponents tempo loss by deploying a massive threat to close the game quickly
However, Grand Unifier offers heaps of power and versatility
With Zombify, however, you can discard a powerful legendary creature to Fear of Missing Out, Bitter Reunion, or Bitter Triumph and bring it back to life as early as turn four
For example, if two creatures you control with lifelink deal combat damage at the same time, Excalibur II's ability will trigger twice
(Each in the mana costs of permanents you control counts toward your devotion to green.) Other creatures you control have trample
And with its ability to copy Eldrazi spells and their triggered/activiated abilities, players can expect EXPLOSIVE turns from this deck
