Patient Disciple

Lifelink
When Patient Disciple enters, reveal the top card
of your library. If that card's mana value is less than
or equal to the amount of life you gained this turn,
put it into your hand. Otherwise, you may exile it.
Plot {1}{w} (You may pay {1}{w} and exile this card
from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)
