Memoria eidética de Proft

If you haven't drawn more than one card by the time a beginning of combat step begins on your turn, Proft's Eidetic Memory's last ability won't trigger at all.

Proft's Eidetic Memory's last ability looks at how many cards you've drawn this turn, even if it wasn't on the battlefield when you drew those cards.

The value of X is determined only once, as Proft's Eidetic Memory's last ability resolves.
