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)

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

It is hard to know how important it is to keep your land count up compared to the spell you are considering countering

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

Valkyrie Harbinger Valkyrie Harbinger is a perfect fit for lifegain focused decks that want steady value over time
