Cards like Dragon Fire and Be Prepared help control the board
But I wouldnt recommend including more than 60 cards in your deck
Anywhoos, back to the preview
Omen of the Sea Other Omens from the Theros Beyond Death cycle like Omen of the Dead share the ability to scry when sacrificed, but Omen of the Sea also does it as its primary ability
Oran-Rief, the Vastwood won't always work, but it's great when it does, and Kessig Wolf Run is a fun use of excess mana should we have it
Blue will bring the ability to draw enough cards to keep going and return annoying permanents to your opponents hands, black brings with it graveyard tutors and the ability to return permanents from your graveyard to the battlefield and green gives us removal pieces to deal with some common graveyard hate effects, plus some of the heaviest hitters in the format that are worth reanimating
