counter deck mtg commander Magic the Gathering: Edge of Eternities – Double Infinity Gaming Counter target spell. The 10 Best +1/+1 Counter

Lets start with Summon: G.F

It does put you down a card, but it is still an incredibly powerful way to protect whatever you are doing on your own turn, and the ability to hit opponents' commanders and large creatures even while tapped out is notable

The excess mana is ideal for spells with X in their cost, which can let you deal lethal damage outright

The cards text box is just ridiculous: it combines Exploration and Crucible of Worlds, two cards that players are happy to pay full price for, on a single body with no mana cost markup

Sapphire/Steel is already a potent color combination, so there's a good chance you can take this deck and turn it into something great
