Grixis Charm Early Game : Yes Parity : Yes Ahead : Yes Behind : No There are few cards that have as wide a range of effects as Grixis Charm
Its not hard to set up a huge attack just by casting noncreature spells
You pay all costs and follow all normal timing rules for cards played this way
Then, once it gets destroyed, you get to manifest the top cards of your library equal to the number of counters on it
There are endless cards in the format with massive mana values that do a splashy thing, so keeping these on the list doesnt make a ton of sense
Honorable Mention #2: Tradewind Rider If this list were Top Ten Spirits for Standard, this would be a clear #1 since it dominated the era with multiple egregious decks like Trade-Geddon where you cast Armageddon and then bounced every new land with this, which I built, or Trade-Awake with Awakening to untap each turn all stuff for more bounces
