makes this card and the card to it's immediate right NOT be in any situation where it could be chosen, ie:
ceremonial dagger and madness wont choose the joker, invisable joker wont duplicate the joker, blueprint will skip over them, brainstorm will pick the leftmost joker which isnt affected by "in the corner",
ITC will prevent verdant leaf from seeing you selling that card, crimson heart will never select ITC or the card to it's immediate right
wheel of fortune will ignore those 2 jokers, temperance will not give you those 2 card's sell values, ectoplasm will never select those 2 jokers
references i wanna mention:
the specific name "math joker" is in reference to it putting these 2 jokers in a separate group from the other jokers. the background in the card is in reference to alan becker's animation vs math. the orange face is a reference to alan becker's animation vs animator where TSC is in that video. theres an omega in the middle for no reason other than i thought itd be funny to see through the head. the E in JOKER has been turned into an e for euler's number.
