mtg timey wimey commander deck Magic Doctor Who facing alien threats Doctor Who MTG Commander Deck:

Prerelease players receive a collectible d10 spindown crystal counter for each event they attend (available while supplies last)

So yeah if you want to open packs of this set, and you probably do, make sure you buy a sealed box and that you do it before the end of the first distribution wave

This direction is shown with cards like Laelia, the Blade Reforged and Wild-Magic Sorcerer, or Prosper, Tome-Bound if you add black mana

Anything that is looking for the "natural result" is looking for the number shown on the face of the die before these modifications

Plus, it has a nifty additional effect that the controller of the spell it counters can't cast anymore spells this turn
