Above the display of cards that show what you can add to your deck is a search bar, and filters for colors and lands
Glue Dots included to adhere your gift card
Cross Crusader is your primary searcher, you almost always want to go into him first, or at least as soon as you've already set up Malicious in the GY, Wonder Driver is your most important combo piece, and Dread Decimator boosts the ATK of all HERO monsters he points to, including himself, and can deal piercing
Combined with the low average cost of cEDHs best playables, Ad Nauseam might as well read Pay five mana, draw 20 cards. This is obviously one of the best things you could do in the entire format, especially alongside the other cards on this list (Demonic Tutor to find your last missing piece, anybody?)
Bidoof is classified as a 1-Diamond card in the Space-Time Smackdown set
