Magic: the Gathering’s control decks usually configure their deck in the way that they would have the card advantage in the late game while setting up their threats that will overwhelm the board. What I would mean of this card advantage are deck manipulation and card draw spells. In today’s Throne of Eldraine card preview, we have one Blue instant that is a possible inclusion in the list of future Blue-based control deck. Check out Into the Story:
The seven-mana cost makes you consider it not as a playset in your deck unless you have plans to have Library Mill as your main deck strategy. If you look at the current list of Esper Control in Standard, they carry only like two to three card draw spells. They focus at first on an immediate answer to threats with spot removals and counterspells. Also, planeswalkers such as Teferi gives them card advantage with the cantrip effects. The correct number would just be two copies to avoid drawing the card early and just let it clog there in your early turns. The drawn four cards are just a good replenish in the late games.
Wrapping up this post and until next time.
