Commander: Nekusar

This is my ongoing development on a Grixis goodstuff deck. It originated from a casual 60-cards Sphinx-deck in Grixis colors which mainly featured early sweepers (Pyroclasm, Damnation) and pinpoint-removal (Terminate), mana-fix and card-draw (Courier's Capsule), into mid-game Sphinxes (and more card-draw) into the late-game Cruel Ultimatums and Nicol Bolas Planeswalkers, Comet Storms etc.

Building it EDH-style enables more mana-intensive sweepers like Decree of Pain, powerful card-draw in Recurring Insight and other fun spells.

The deck plays surprisingly well, with random react-spells like Sudden Spoiling, some counters in Undermine Suffocating Blast and Time Stop.

With all the Sorceries and Instants, Mnemonic Wall and Charmbreaker Devils are quite nice. Make some extra copies with Tempt with Reflections (or Rite of Replication) to return the copy-spell itself and some extra Sorceries to your hand. Also, the Primordials, Titans and Bogarden Hellkites make enough copy/clone targets.

Also, the copy-mages Nivix Guildmage and Echo Mage can do some crazy stuff. Imagine double or triple Cruel Ultimatums. Please note, that these don't work when copied:
All mass removal (duh)
- Time Stop (stack is emptied)
- Psychic Spiral (graveyard is empty after the first)

And these work less good because:
- Comet storm -> You can just multi-kicker it, exept when you already multikickered it enough that it's more mana-efficient to use a Mage (Echo Mage full-leveled)
- Diabolic Revelation -> Just pump more mana into X
- Profane Command -> You can't choose new modes


Nice endgame killer: Wild Ricochet -> recently I was targeted with a lethal damage-X-spell and reflected it with a copy to it's caster. Nice Game.
