mtg cards that double counters MtG: In the Spotlight: Doubling Season and it isnt legendary Doubling Season (Toppers) [Double Masters]

Sol Ring is so ubiquitous to the format that it's shown up in almost every Commander preconstructed deck ever released

And when it flips, combat changes completely

These 1-drops then get replaced with ninjas via the nunjutsu mechanic to quickly build up and army of aggressive, strong threats

Vigilance is common among soldiers, but trample and haste are much harder to come by and valuable for pretty much any other commander on this list

Granted they enter tapped, but if you can station them sufficiently, these two lands do a decent imitation of Gaea's Cradle and Tolarian Academy, two busted lands from Urza's Saga
