function:ramp mv=1
Find card with exact card name. Then, you can use the button at the top of the page to see all illustrations of the card. Very useful when you want to pick specific illustrations for your proxies

Find full art lands. Make sure to change the display to 'All prints'

function:"multiple targets" legal:modern -legal:pioneer mv<=3
Searching for more than one card type. I used this when looking for cards whose cost I could reduce with Locket of Yesterdays in storm
(type:instant or t:sorcery) (game:paper) mana>={2} legal:modern prefer:best
