As far as I know, there is only one card that has more than 2 illustrator: Azumi Kagamihara. She has Takuya Fujima, Airi Horizumi on Zekkai no Crusade PR, and Gin on the chocolate PR. Other than her, perhaps Mikado & Ayase would be qualified if we included the Player Cards from Starter Deck Vol.3 (no illustration credit on the cards, just "Z/X Ignition Production Committee" text).

Now for the placement. Perhaps the safest bet is to put it on the bottom of card image, or put it just above the gallery link.
