Everyone's Friend (EDH / Commander)

Help those that don't hurt you

Almost every card gathered in this deck is beneficial to every player at the table. There are cards that help every player with mana ramping, like Collective Voyage, Rites of Flourishing, and Tempt with Discovery. Others that double the amount of mana that each player gains from tapping land, like Dictate of Karametra and Heartbeat of Spring.

Some that reduce the cost of spells for everyone, like Arcane Melee and Helm of Awakening. Still other cards that create copies of spells for all to use, like Tempt with Reflections, Fractured Identity and to a somewhat more or less extent, Eye of the Storm (really like this card for this kind of deck lol) and Tempt with Vengeance. There are cards here to set cards into the battlefield for free, like Braids, Conjurer Adept or Hypergenesis. And of course, things to let people draw more cards, sometimes only if they want to.

The point of this deck: accrue life, cause some chaos and mayhem during the game, and when someone decides to attack you.... Obliterate them with Defensive cards like Disallow, Eye for an Eye, Harsh Justice, Settle the Wreckage, Spelljack, Swerve, Storm Herd or one of the few Wall creatures that are in it. And when it comes down to you and one other player. Play Ajani Goldmane's Ult, Beacon of Immortality, cast Rite of Replication and kick it, then attack, Time Stretch, attack, Beacon of Tomorrows, attack. Using counters and/or Eye of the Storm when applicable.
