Proft's Eidetic Memory

Description

Proft's Eidetic Memory (MKM-67) is a legendary enchantment from Murders at Karlov Manor that costs {1}{U}. It gives you no maximum hand size, draws a card when it enters, and can put X +1/+1 counters on a creature at the beginning of combat on your turn if you've drawn more than one card that turn. The last ability calculates X as the number of cards drawn that turn minus one and resolves as a single effect targeting a creature you control.
