Felkian, Enchanting Host

Parley—at the beginning of your upkeep, each
player reveals the top card of their library. You
gain life equal to the highest converted mana cost revealed this way.
{t}: Gain control of target creature with power
less than or equal to the amount of life you
gained this turn until end of turn. Untap that creature. It gains haste until end of turn.
Whenever a creature you control but don't own
deals combat damage to their owner you
draw a card.
